Shape memory in magneto-auxetics

dr hab. Mirosław R. Dudek, prof. UZ

A novel class of metamaterials having magnetic insertions embedded within a non-magnetic auxetic matrix is under discussion. It is shown that such systems can exhibit a series of anomalous properties which include tunable Poisson’s ratio as well as ferromagnetic and shape memory behaviour. Recently, the magnetocaloric effect (MCE) exhibited by magneto-auxetic systems in the vicinity of room temperature was discussed. Some features, like the system negative thermal expansion property for shape recovering was presented.
