Magnetic anisotropy (MA) is one of the most important material properties for modern spintronic devices. Conventional manipulation of the intrinsic MA, i.e., magnetocrystalline anisotropy (MCA), typically depends upon crystal symmetry. Extrinsic control over the MA is usually achieved by introducing shape anisotropy or exchange bias from another magnetically ordered material. Here we demonstrat...

Given the paucity of single phase multiferroic materials (with large ferromagnetic moment), composite systems seem an attractive solution to realize magnetoelectric coupling between ferromagnetic and ferroelectric order parameters. Despite having antiferromagnetic order, BiFeO3 (BFO) has nevertheless been a key material due to excellent ferroelectric properties at room temperature. We studied a...

In recent years, functional oxide-metal based vertically aligned nanocomposite (VAN) thin films have gained interest due to their intriguing physical properties and multifunctionalities stemming from the complex interactions between two phases in film substrate. this work, we develop a model for studying energetics of these systems, including effects both lattice mismatch capillary forces inter...

Amorphous/crystalline mixed La0.5Sr0.5MnO3 (LSMO) thin films on quartz wafers are prepared at different depositing temperatures using laser ablation and their lowfield magnetoresistive property is investigated. It is argued that the insulating amorphous layers separating the magnetic microcrystalline grains may act as the barriers for electron tunneling. The rapid decay of magnetoresistance wit...
