Abstract

We report on the magnetic properties of epitaxial La _0.7Ba _0.3MnO ₃ and La _0.7Sr _0.3MnO ₃ films on Si (100) and Si (111) substrates using SrTiO ₃ template layer, which demonstrate magnetic and electrical properties at and above room temperature. The magnetization data show magnetic transition and magnetic hysteresis at and above room room temperature. The films show well-defined magnetic domains. The ferromagnetic resonance studies show anisotropic effects related to ferromagnetic properties of films. The smaller grain size of about 20 nm in manganite films on SrTiO ₃/Si may be one of the reasons to minimize the strain effect through strain relaxation at the interface between SrTiO ₃ and manganites through the formation of three-dimensonal islands.
