Perovskite oxides (ABO3) show wide range of functionalities originating from interplay of structural, spin, charge, and orbital degrees of freedoms. The bulk perovskite structure could be controlled via conventional chemical substitution, though exploiting heterostructure engineering novel ground states could be observed which otherwise are absent in bulk. In this thesis, the interest is to explore the electro-magnetic phenomena as complex oxides are confined in heterostructures.
I first investigate electromagnetic properties of ultrathin epitaxial ruthenate: SrRuO3 (SRO); spatially confined between SrTiO3 (STO) i.e., STO5-SROn-STO5 with n = 1- and 2-unit cells. It …
