Abstract

In order to evaluate the effect of charge transfer and/or charge ordering in (formula presented) on the magnetic and transport properties, a library of (formula presented) superlattices have been fabricated by the combinatorial pulsed laser deposition method. The properties of superlattices were found to depend strongly on the periodicity m; superlattices of (formula presented) behaved like a solid solution (formula presented) film, while the superlattices of (formula presented) were significantly different from the solid solution. These superlattices exhibited a higher resistivity and lower Curie temperature than (formula presented) superlattices. The results indicate that the properties of the superlattices are dominated not only by the magnetic interaction between the superlattice constituents but also by carrier (formula presented) electrons) transfer thorough the superlattice interface. The contribution of carrier transfer is supported by the magnetoelectric properties of another library of (formula presented) superlattices. The A-site cation order can change both effective carrier concentration and magnetic interaction.
