A direct consequence of the partial filling of the f shell is the possibility of localized of magnetic moments in the tested compounds and their spontaneous organization in a (usually very low) temperature. Interactions leading to the order areaccompanied by the interactions that destroy that order. The competition of these two processes results in the presence of a wide range of poorly studied physical phenomena such as the formation of superheavy quasiparticles (i. e. heavy fermions), unconventional superconductivity, or non-Fermi liquid behavior. A detailed description of these phenomena cannot be found in academic textbooks and their description is one of the major challenges of modern solid state physics.

The Division also specializes in experimental and theoretical studies of electron transport phenomena occurring in single crystals of lanthanum compounds and actinides. Among lanthanide compounds a lot of attention is paid to the ones in which the Kondo effect, splitting of the 4f states in the crystalline field as well as magnetic and quadrupole ordering have a visible impact on the properties of electronic transport. Of high interest are also regular LaMe3 compounds as well as filled arsenide scutterudites arsenic - LaT4As12 (La - lanthanide; Me - Sn, Pb, In, Ga, T - Fe, Ru, Os). Arsenide scutterudites filled with a lanthanide have been obtained in the Division in the form of single crystals for the first time in the world. These arsenide scutterudites, like the previously studied by other authors filled phosphoride and antimonide scutterudites  (the so-called thermoelectric rattles), have a great wealth of physical properties that are the driving force behind the scientific and technological interest. Research of actinide compounds led the Division to detection of the existence of:

1. non-magnetic Kondo effect of structural defects in crystals, both diamagnetic thorium pnictochalcogenides and ferromagnetic uranium pnictochalcogenides
2. ferromagnetic semiconductor (ThxU1-x)3As4 with potentially interesting spintronic properties.

As one of the few in Poland,  for many years the Division has specialized in studies of NMR of nuclei of s, p and d-electron elements in alloys and intermetallic compounds. These hydrides and borides of transition metals and intermetallic compounds of these elements involving rare earth and uranium, which are extremely important from the point of view of their practical applications. They show a great wealth of physical properties: from the semiconductor nature to magnetic, quadrupole ordering or heavy-fermion properties. It has been recently shown that the use of techniques of high-speed rotation at the magic angle (MAS) at the resonance of "heavy" nuclei ¹¹⁹Sn and ¹⁹⁵Pt allows to obtain multiplet structure of the spectra of resonant compounds TiPtSn and ZrPtSn, thereby detecting the effects of scalar and covalent nature of the chemical bonds in these compounds. On the other hand, studies using a "light" core ¹¹B in a number of borides: YB4, YB6, YB12, ZrB12, or 12 allowed to determine the size of components of the electric field gradient (GPE) tensor in boron atoms positions. These values have allowed to validate theoretical calculations of the electronic structure, which lay down the GPE tensor for these compounds.

Another specialty of the Division is the work on metal hydrides:

1. Low- and high-pressure synthesis of new hydride phases.
2. Investigation of the effect of hydrogen on the structural and magnetic properties of complex intermetallic compounds of rare earth with d-metals.
3. Studies on the properties of hydrogen absorption by Mg-Ni alloys synthesized using mechnical milling.
4. Characterization of hydride systems using method for testing the pressure equilibrium isotherms as a function of the concentration of hydrogen.
5. Studies of thermodynamic properties of the MAX d-metal triple carbide phases using low-temperature calorimetry.

Oddział zajmuje się badaniem (zarówno doświadczalnym, jak i teoretycznym) zjawisk zachodzących w układach silnie skorelowanych elektronów, czyli takich, w których elektrony ze zlokalizowanych powłok f silnie oddziałują z elektronami z pasma przewodnictwa. W praktyce są to związki chemiczne, w których co najmniej jeden ze składników jest pierwiastkiem posiadającym częściowo zapełnioną powłokę elektronową f, czyli lantanowcem lub aktynowcem. W Zakładzie Badań Magnetycznych badane są przede wszystkim związki oparte na cerze, iterbie i uranie. Związki oparte na innych lantanowcach i aktynowcach są również badane, jednak stanowią zdecydowaną mniejszość w licznych projektach badawczych realizowanych przez Zakład.

The curriculum is based on modules of various lengths (from one to several semesters), which consist of cycles of interesting activities of various subjects and character (lectures, exercises, laboratories, seminars, popularization of science) to be realized in almost any order throughout the entire period of education. In the case of most modules, doctoral students and their supervisors select from the available pool the most valuable activities in their research and scientific career. As it befits an international school, education at WSD IPAN is provided in English.

The subject modules at WSD IPAN are the following:

• TOOLS - Tools for the investigator's workshop
  
  During these classes, our Ph.D. students learn how to plan research, write grant and patent applications, analyze data, edit articles, prepare conference presentations, etc. - the "must-have" of every scientist.

• GENERAL - Research methods and general issues
  
  A series of several-hour-long lectures by experts presenting in an accessible way the research methods used in research in modern science (both experimental and theoretical). These classes are not only about getting to know the tools of other scientists - they also mean broader horizons, courage to speak at scientific conferences and self-confidence in the scientific discourse.

• ADVANCED - Advanced topics
  
  During these classes, PhD students of WSD IPAS get to know the area of research closest to their doctoral dissertation and become experts in their discipline.

• INTERDISCIPLINARY - Interdisciplinary classes
  
  Classes for those not afraid to see physics and chemistry in biology.

• SEMINARS - Seminars
  
  Every scientist must be able to listen and talk to others in such a way as to be understood. Seminars at WDS IPAS, conducted at various levels and for miscellaneous audiences, teach this.

• PRACTICAL – Practical training
  
  The theory is not enough – a scientist needs an apron, glasses, gloves, modern equipment, and much pleasure in doing research. Ph.D. students of WDS IPAS don't have to take anyone's word for it - they can verify everything for themselves or prove it experimentally to others.

• ENGLISH - English language course
  
  Weekly conversations with a native speaker (optional), for ambitious students, for even greater self-confidence.

Topics for student training in the Institute along with the regulations and application procedure can be found on pages available only in Polish. Students, who would like to learn the details should contact directly the advisors.
