Finally, the increase in the magnetic interfacial coupling produces an increase in coercive field and a decrease in the exchange bias field.Īrcher T, Hanafin R, Sanvito S (2008) Magnetism of CoO polymorphs: density functional theory and Monte Carlo simulations. In addition, the magnetization reversal is not perfectly uniform in space when the interfacial coupling is different from zero. The numerical results reveal, as expected, a significant hysteresis loop shift obtained for a weak interface coupling. Monte Carlo simulations performing single spin rotation are used to investigate the effect of exchange bias on the spin configurations and hysteresis loops of core/shell nanoparticles. Our magnetic simulations are based on a 3D classical Heisenberg model. Two different configurations of core/shell NPs were examined: homogeneous and inhomogeneous core/shell. The numerical core/shell is built by taken into account the spinel structure of the core (Fe 3O 4) and the face-centered cubic structure of the shell (CoO). The nanoparticles (NPs) consist of a perfectly epitaxial crystalline cobalt oxide (CoO) shell on a magnetite (Fe 3O 4) core. The present work focuses on the study of exchange-biased magnetic core/shell nanoparticles at the atomic scale. ![]()
