“…[5,6] below the room temperature crystal structure of La 2/3 Ba 1/3 MnO 3 manganite represents a mixture of the high temperature rhombohedral R3c phase (austenite) and the low temperature orthorhombic phase Imma (martensite) as a result of martensitic phase transformation. It occurs over a wide range of temperatures [5,6] that is typical for transformations of such type [7,30]. Note, that on cooling, a martensitic transformation starts at the martensite start temperature M s , and finishes at the martensite finish temperature M f .…”
