Study of the modified magnetization resulting from interfacial electronic reconstruction in LaSrMnO/BaTiO hybrid multiferroics

DOI

Multiferroics are promising candidates for faster and cooler electronics. Due to the intrinsic incompatibility between the ferromagnetic (FM) and ferroelectric (FE) phases, it is challenging to take advantage of the magneto-electronic coupling in single-phase materials. Fortunately, perovskite oxide FM/FE hybrids provide an alternative pathway to the functionality. Our focus is on heterostructures of ferromagnetic La0.7Sr0.3MnO3 (LSMO) and ferroelectric BaTiO3 (BTO). Preliminary X-ray Magnetic Circular Dichroism and Polarized Neutron Reflectivity measurements on this system have given evidence of an induced moment of the Ti ions of BTO. We aim to further explore bilayers and a trilayer in order to solidify these observations, determine the depth profile of the measured Ti moment, the sign of the exchange interaction with the adjacent Mn in LSMO.
