Abstract
Abstract
The Stoner–Wohlfarth (SW) model is a very lucid way of describing the dynamics of a single domain particle whose switching properties are important for storage applications such as magnetic random-access memory. This model explains the ideal case hysteresis and angular dependence of magnetization curves of aggregation of single domain particles with uniaxial anisotropy. Based on the energetics of a ferromagnetic particle and using atomistic simulations solving the Landau Lifshitz Gilbert equation, we study the hysteresis loop of a 1 nm ellipsoidal cobalt nanoparticle. The simulated M–H plot also displays the hysteresis branch crossing behavior when the field is applied close to the hard-axis.
