Abstract

Measurements of the magnetocapacitance effect in epitaxial La_0.7Sr_0.3MnO₃/Pb(Zr_0.2Ti_0.8)O₃/La_0.7Sr_0.3MnO₃ heterostructures have been performed using a quasi-static method. Through capacitance-voltage measurements carried out under variable magnetic field it has been found that the magneto-capacitance depends on the orientation of the ferroelectric polarization. The value of magneto-capacitance can be as high as 1% in the voltage range near the ferroelectric coercive field. This has been attributed to a variation of the apparent built-in voltage of the PZT-LSMO Schottky barriers on applied magnetic field.
