The phenomenon of conversion polymorphism in Bi-containing metastable perovskites
Khalyavin, D.D.; Salak, A.N.; Fertman, E.L.; Kotlyar, O.V..; Eardley, E.; Olekhnovich, N.M.; Pushkarev, A.V.; Radyush, Yu.V.; Fedorchenko, A.V.A post-synthesis thermal treatment of metastable phases in the high-pressure stabilised perovskite BiFe1-yScyO3 system results in the irreversible formation of polymorphs which represent novel polar and antipolar structures with interesting magnetic properties. Such annealing-stimulated polymorphism is believed to be a general phenomenon which can be found in other systems.
