Abstract:We propose a freezing ferromagnetic moment model to explain the exchange bias discovered in alpha-Fe2O3 antiferromagnetic nanoleaves most recently. The model assumes that in the antiferromagnetic nanosystem, the disorder surface spins are frozen at low temperature along magnetic filed direction, forming a ferromagnetic layer. Then this results in an exchange bias. After some proper simplification, we get the magnetization at different applied field by the minimal energy calculation using MATLAB.
