Magnetization and Giant Magnetoresistance of the System of Interacting Fine Particles
Abstract
The magnetization and giant magnetoresistance (GMR) of nanosized magnetic particles embedded in a nonmagnetic metallic matrix are numerically investigated. By considering the classical dipolar interactions, we apply a Monte Carlo simulation technique to calculate M vs H, GMR vs H, and GMR vs (M/M delta) with M, the average magnetization along the normal to the layer, M, the saturated magnetization, and H, the applied magnetic field. It is shown that the interfacial spin-dependent scattering of conductance electrons is dominant in GMR effect and the distance between the neighboring particles is an important parameter to obtain the GMR effect, while the size distribution only modify the shape of the curve of GMR versus H.
