摘要

We study a hybrid system of a magnetic oxide thin film on a ferroelectric substrate. We show that magnetic and transport properties of the magnetic oxide film strongly depend on the dielectric constant and polarization of the ferroelectric substrate. Tuning these parameters one can induce the metal-insulator transition in the magnetic oxide film accompanied by the ferromagnetic to superparamagnetic transition. Ferroelectric properties can be tuned by varying temperature or applying an electric field.
