Abstract

Polycrystalline ZnO/La_0.7Sr_0.3MnO₃ (LSMO) heterostructures were fabricated onto Si(100) substrates by magnetron sputtering. A rectifying behavior, as well as an enhanced magnetoresistance (MR) ratio (∼ 12%), was obtained in the heterostructure with respect to the LSMO single layer (a MR ratio - 6%). The degradation of the rectifying behavior for the LSMO layer thinner than 20 nm is mainly due to the change in hole concentration. We suggest a possibility that the magneto-transport and the magneto-optical properties of manganites can be modified by the formation of this kind of heterostructure.
