Preserved Fulltext
Multiferroic double-perovskite BiFe 0.5 Mn 0.5 O 3 thin film heterostructures were epitaxially grown on CaRuO 3 -buffered (001) SrTiO 3 by pulse laser deposition. Typical Vogel-Fulcher relaxorlike dielectric and magnetic susceptibilities were observed, implying the film exhibits the properties of an electric relaxor and a magnetic relaxor. Polarization and size of polar nanoregions (PNRs) were determined by fitting the dielectric constant to a multi-polarization mechanism model. It was found
