FE Switching in SrRuO3/NiFe2O4/BaTiO3/LSMO Heterostructures on SrTiO3Substrates

This work reports the successful fabrication of an all-oxide heteroepitaxial structure with a bilayer tunnel junction consisting of ferroelectric and ferrimagnetic layers. Each layer of the structure exhibits high crystallinity and well-defined interfaces. The transport properties of the junction are found to be well described by the characteristics of an asymmetric ferroelectric tunnel junction.
