FIG. 1.

Magnetization curves at three temperatures slightly below . They display the first quadrant hysteresis expected for martensitic crystals with magnetic anisotropy density greater than the blocking stress.

(a) Magnetization loops measured at 250, 150, and , characterized by multiple slope changes with changing field. (b) Second derivative of the magnetization as a function of at corresponding temperatures. The insert shows the field dependence of the first derivative of the magnetizations.

Image of FIG. 3.
FIG. 3.

(a) Temperature dependence of saturation magnetization and magnetic anisotropy constant of martensitic . The uncertainties of the anisotropy field can be evaluated from the lack of the definition of the cusps in Fig. 2(b). The resulting error bars of have been included in (a). (b) Dependence of vs for , 3, and 4.
