(a) Capacitance-voltage characteristics at different magnetic field acquired at 75 K and 1 kHz on a LSMO-PZT-LSMO sample with 50 nm PZT film thickness; (b) a zoom-in of (a) in the peak region associated with the polarization switching. The inset in (a) shows the measurement geometry; (c) Dielectric loss-voltage characteristics acquired at different magnetic fields.
