Electric field effects on magnetotransport properties of multiferroic Py/YMnO<sub>3</sub>/Pt heterostructures
Electric field effects on magnetotransport properties of multiferroic Py/YMnO<sub>3</sub>/Pt heterostructures
We report on the exchange bias between antiferromagnetic and ferroelectric hexagonal YMnO3 epitaxial thin films sandwiched between a metallic electrode (Pt) and a soft ferromagnetic layer (Py). Anisotropic magnetoresistance measurements are performed to monitor the presence of an exchange bias field. When the heterostructure is biased by an electric field, …
