Study of magnetic correlations in nanostructured ferromagnets by correlation magnetometry

Abstract

We propose a theoretically justified experimental magnetometric technique for determining the size of stochastic domains spontaneously formed in the spin system of nanostructured ferromagnets and for evaluating the effective anisotropy in these magnetically correlated regions. The method is based on monitoring the ΔM∼ H−2 relationship in the low-field part of the integral magnetization curve.
