Competing interactions and complex magnetism at SrRuO{sub 3}/SrMnO{sub 3} interfaces.
The coupled interfacial Mn and Ru spin configurations in a SrRuO{sub 3}(SRO)/SrMnO{sub 3}(SMO) superlattice are investigated with x-ray resonant techniques. With an out-of-plane applied field H, a net Mn moment is induced opposite to (along) H below (above) SRO Curie temperature T{sub C}, due to changes in interfacial antiferromagnetic Ru-Mn coupling. In comparison with the Mn moment induced along an out-of-plane field below T{sub C}, the Mn moment induced along an in-plane field is five (three) times smaller below (above) T{sub C}, due to frustration in the Ru-Mn coupling. Despite its in-plane anisotropy, the G-type antiferromagnetic SMO favors out-of-plane over in-plane canting of Mn moments.
