Coupling and interface effects in magnetic oxide superlattices

Magnetic oxide superlattices are attractive model systems in which to study coupling and interface effects. After briefly summarizing synthesis and characterization methods, this review describes recent experimental results obtained in investigating epitaxial oxide, multilayers comprised primarily of ferromagnetic/paramagnetic, ferromagnetic/antiferromagnetic, and antiferromagnetic/antiferromagnetic materials. The results are discussed in terms of their implications for exchange coupling, exchange biasing, and novel magnetic structures.
