Abstract

We report on the integration of epitaxial colossal magnetoresistive La_0.67Ba_0.33MnO films on Si(100) semiconductor using SrTiO₃ template layer by pulsed-laser deposition. X-ray diffraction reveals the superior quality of the manganite film that grows epitaxially on heteroepitaxially grown SrTiO₃ template layer on Si substrate. The epitaxial films demonstrate remarkable surface morphology, magnetic transition and hysteresis, magnetoresistance, and ferromagnetic resonance, illustrating the ferromagnetic nature of the film and possible device applications at room temperature.
