(a) Isothermal magnetization recorded at several temperatures. (b) Temperature dependent in-phase component of magnetic ac susceptibility, , for different frequencies . The inset shows the enlarged version around ZFC cusp (near 28 K) for LBMFO.
Temperature dependence of the real and imaginary parts of permittivity on different magnetic fields. The inset shows the magnified view near the weak dielectric anomaly (around 62 K).
(a) Temperature dependence of electric polarization in an applied field of . (b) Electric field-dependent polarization reversal at low temperature on different applied field directions. The arrows and number of steps indicate the way the measurement is made; see text for details (solid lines are guide to the eyes).
