Abstract

We have synthesized and characterized doped manganite trilayers composed of La0.7Sr0.3MnO3 (LSMO) and La0.7Ca0.3MnO3 (LCMO). Because of the isostructural nature of the Sr and Ca doped manganites, trilayers exhibit good epitaxy as observed in X-ray diffraction. Magnetization measurements reveal magnetization values consistent with bulk values. In-plane transport of these trilayers reveals anisotropic magnetoresistance and high field negative magnetoresistance attributed to the suppression of spin fluctuations at high fields.
