Abstract

Herein, for the first time, a model is developed for the description of magnetoresistance in nanosized, granular Sr2FeMoO6–δ–SrMoO4 core–shell structures, which is based on the fluctuation‐induced tunneling model. Parameters of the fluctuation‐induced tunneling model of granular materials are calculated. The magnetic field is considered to affect the tunneling barrier height. The linear and quadratic coefficients of this effect are estimated.
