Stress-strain curve of sample with the single highly mobile twin boundary (compression). The initial and final twin configurations in reference to magnetization experiments are schematically presented as insets with the direction of c-axis or easy magnetization axis indicated by arrows.
Magnetization curves obtained at 300, 150, and 20 K. Jumps of the magnetization curves associated with the twin boundary motion or MIR are marked by arrows with label “MIR.” Switching field, i.e., the field at which these steps were detected, is labeled as ; at selected temperatures is given in inset.
(a) Calculated magnetic stress as a function of the applied field at selected temperatures. (b) Calculated twinning stress as a function of temperature (full red squares—studied alloy, empty dotted blue squares—additional measurement on an alloy with IMT around 190 K). Data from Ref. 12 (crosses ) and Ref. 18 (crosses x). Lines are only visual guides.
