  • Abstract
    Magnetic thin film Tb(FeCo) plane were studied under various applied delay times under a series of magnetic field to understand the factors of asymmetry of microhysteresis loops. The delay time of the applied magnetic field increased with a decrease in bulk coercivity while the asymmetrical behavior of the coercivities lead to a magnetization reverse process. The plot of Preisach diagram from 90,000 microhysteresis loops have provided the direct measurement tool for testing Presiach model.
