Abstract

Multiferroic heterostructures of the ferromagnetic, half-metallic Heusler Fe₂CrSi (FCS) and the ferroelectric perovskite Ba_0.7Sr_0.3TiO₃ (BSTO) have been formed by magnetron sputtering, and their magnetic and ferroelectric properties have been investigated. FCS/BSTO bilayer structures were epitaxially grown on LaAlO₃ substrates with epitaxial relationships of FCS (001)[110]//BSTO (001)[100]. Multiferroic properties with a remanent polarization of 10.6 μC/cm² and a saturation magnetization of 417 emu/cc were observed for the FCS/BSTO heterostructures at room temperature. These results suggest that the Heusler/perovskite epitaxial heterostructure is a promising candidate for fabricating multiferroic devices.
