Figure 2. (a) Specific heat normalized by temperature (CP/T), (b) magnetizations (M) under the ZFC and FC conditions, (c) dielectric constant (ε), and (d) released current (Itot = Ipyro) by the mPyro method at a warming rate of 2 K/min with a poling electric field Epole = 10 kV/cm, as a function of T, respectively.
The dielectric constant was measured at frequency of 100 kHz with a bias of 50 mV, and no remarkable frequency dispersion was observed. The phase regions proposed in literature are labeled on the top.
