Multiple ferroic glasses via ordering

摘要: Abstract Structural glasses are characterized by the loss of long-range translational and rotational symmetry. In last two decades, however, it has been discovered that materials exhibit ferroic (ferromagnetic, ferroelectric ferroelastic) phase transformations may also glassy behavior, in which degrees freedom (magnetization, polarization, strain) a A consequence this symmetry is suppression transitions. Moreover, these unique systems dynamic thermodynamic behavior analogous to regular structural glasses. Conventionally, onset brought about introduction spatial heterogeneities, typically originating from point defects, particularly case strain Here, we demonstrate, for first time, configurational order/disorder single ferromagnetic alloy (Ni 45 Co 5 Mn 36.6 13.4 ) can be used stabilize both magnetic The control degree order – through simple heat treatment schedules –, simultaneous application stress field enabled us observe Kauzmann point, is, collapse entropy difference between crystalline phase. Systematic investigation transformation system as function four kinds solid–solid transitions (ferromagnetic–paramagnetic, martensitic transformation, glass) composition. investigated further elucidate nature glass their coupling.
