Magnetization Processes of Nanoparticles Embedded into Ferromagnetic Matrix

Title variants
Languages of publication
The paper refers to computer simulations of interactions between magnetically hard particle embedded into ultra-hard matrix. We used simulated annealing and Monte Carlo simulations in a frame of the 3D Heisenberg model. The performed simulations reveal that the particles show additional exchange anisotropy dependent on "frozen" spin direction in the matrix and the angle between matrix and particle easy magnetization axes. The particle-matrix coupling are responsible for multi-phase magnetic hysteresis shape and exchange-bias like effect.
