Multiple ferroic glasses via ordering

Simple heat treatments in the Ni45Co5Mn36.6In13.4 magnetic shape memory alloy leads to the observation of multiple first and second order phase transitions including strain and magnetic glassy states through change in the degree of configurational order. Phase diagram above shows the influence of heat treatments on the Curie (TC), martensite start (TMs), spin glass freezing (Tf), supercooled austenite (T∗), strain glass freezing (Tg) and Kauzmann (TK) temperatures.125
