Abstract
Ferromagnetic spin order has been realized in the LaCrO
3
-LaFeO
3
superlattices. Ferromagnetic coupling between Fe
3+
and Cr
3+
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 Fe
3+
and Cr
3+
ions has frustrated the observation of ferromagnetic properties. By creating artificial superlattices of Fe
3+
and Cr
3+
layer along the [111] direction, ferromagnetic ordering has been achieved.
