Abstract

Ferromagnetic spin order has been realized in the LaCrO₃-LaFeO₃ superlattices. Ferromagnetic coupling between Fe³⁺ and Cr³⁺ through oxygen has long been expected on the basis of Anderson, Goodenough, and Kanamori rules. Despite many studies of Fe-O-Cr-based compounds, random positioning of Fe³⁺ and Cr³⁺ ions has frustrated the observation of ferromagnetic properties. By creating artificial superlattices of Fe³⁺ and Cr³⁺ layer along the [111] direction, ferromagnetic ordering has been achieved.
