ABSTRACT
Multiferroic transition metal oxides exhibit a wide variety of properties that are related to the delicate balance between lattice, charge, spin, and orbital degrees of freedom [1]. Modern thin-lm synthesis methods such as pulsed laser deposition (PLD), molecular beam epitaxy (MBE), and metal-organic chemical vapor deposition (MOCVD), among others, enable the engineering of interfaces between complex transition metal oxides with atomic-scale precision. Interfaces introduce a variety of local changes, for example, they break

the symmetry of the material, induce stress, and lead to variation in the bonding between ions. ese in turn give rise to changes in electronic structure such as bandwidth, orbital interactions, and energy-level degeneracy. Charge transfer in these correlated systems can induce changes in carrier densities at interfaces that result in physical properties that may be completely dierent from those of the parent bulk phases [2-6].
