In mixed valence manganese perovskites the competition between the various types of interactions as double exchange, Jahn-Teller coupling, Coulomb, and antiferromagnetic superexchange which are sensitive to the structural parameters and doping creates a rich phase diagram with various types of magnetic, orbital and charge ordering. Thus they present an ideal system for building exchange-biased antiferromagnetic (AF), ferromagnetic FM superlattices since the structural compatibility of the AF and FM layers permits coherent growth of the superlattice that satisfy the conditions for magnetic coupling at the interfaces.
