Paper Abstract

In this paper, we present an energy-minimization theory of ferromagnetic particles to characterize the magnetization reversal and hysteresis loop of ferromagnetic polycrystals, with the inter-granular magneto-static interactions accounted for through the effective medium approximation. The energy-minimizing magnetization distribution is determined, and the remanence and coercivity are predicted.
