Anisotropic and nonlinear magnetodielectric effects in orthoferrite ErFeO3 single crystals

Abstract In rare-earth orthoferrites, strongly correlated order parameters have been thoroughly investigated, which aims to find multiple functionalities such as multiferroic or magnetoelectric properties. We have discovered highly anisotropic and nonlinear magnetodielectric effects from detailed me...
