Magnetic reversion in real nickel and cobalt nanowires and the angular dependence of coercivity

Abstract

Using micromagnetic simulation we present an analysis about the effects of the microstructure on the angular dependence of coercivity and quadrature. The results return curves profiles that resemble experimental data already reported in the literature. We show that, there is an ambiguity in case of adopting the curve profile of the angular dependence of coercivity as the starting point to assume the predominant reversion mode. We conclude in this study that, to infer any reversal mechanisms always have to take into account the nanowires microstructure.
