Abstract

FeRh based composite multiferroic materials have attracted great scientific interest due to their wide variety of possible applications in future nano device technology. In the recent work, a comprehensive study on the depth dependence of the metamagnetic phase transition in FeRh/BaTiO3 heterostructure is reported by means of single or combined external stimulus such as heat, magnetic or electric field. Grazing-incidence nuclear scattering experiments revealed significant discrepancies in the mechanism of the antiferromagnetic/ferromagnetic reor- dering induced by the different effects, with distinguished role of both upper and lower interfaces.
