Abstract

The transport properties of Mn doped cuprate oxide La_1.85-2xSr_0.15+2xCu_1-xMn_xO₄ and Cu doped manganite oxide La_0.825Sr_0.175Mn_1-yCu_yO₃ are investigated. In both series, the resistivity for the intermediate doping samples exhibits an anomalous decrease. We argue that in both systems, the Cu-O-Cu pdσ path and the Mn-O-Mn double exchange path form mutual percolation paths and contribute to the conductivity. The resistivity data for both systems are fitted by using the mutual percolation model. © 2005 Elsevier B.V. All rights reserved.
