Figure 2. Magnetization and capacitance for different initialization processes.

(a) Magnetization as a function of temperature for samples initialized with different B_ext. The transition temperature can be made to vary from 276 K (B_ext = 0.02 T) to 317 K (B_ext = 0.04 T). (b) Capacitance measurement for several different B_ext corresponding to distinct electrodes configuration (see text and Fig. 1 for details).
