Abstract
We report the GMR-like magnetoresistive behavior of granular ferromagnet-insulator mixtures below the percolation threshold. In contrast with heterogeneous ferromagnet-normal metal systems, the absolute magnitude of the magnetoresistance increases at lower concentrations of the ferromagnetic component, and reaches a field sensitivity Δ ϱ/Δ H of the order of 10 Ω cm T −1. Characteristic features of the GMR in highly resistive granular ferromagnets are discussed.
