FIG. 1.

Magnetization vs temperature plots for annealed and as cast samples of in an applied field of . While plot for the as cast sample was obtained using a SQUID magnetometer, a VSM was used in the case of the annealed sample. The ZFC curve actually overlaps with FCW curve, and is not shown here separately for the sake of clarity.

FIG. 3.

Change in entropy as a function of temperature across the austenite-martensite transition in , measured under three different experimental protocols P1, P2, and P3.
