Description
A modified Stoner-Wohlfarth model to describe an ensemble of ferromagnetic clusters interacting with a quasi-isotropic spin glass was developed to account for asymmetric reversal in concentrated spin glass systems. The model used a Gaussian distribution of cluster easy axes orientations, which successfully simulated magnetic hysteresis loops exhibited by two concentrated CuMn alloys. Physically plausible scenarios for the dependences of model parameters on cooling field were extracted.
