摘要: Through the hysteresis loop and magnetization spatial distribution we study compare two models for surface anisotropy in nanomagnets: a model with transverse axes Neel's model. While induces several jumps because of cluster-wise switching spins, Neel correspond to successive coherent partial rotations whole bunch spins. These calculations together some hints from available experimental results, suggest that is more appropriate.
