Abstract
The influence of the spin reorientation phenomenon on the nucleation field of NdFeB magnets is analyzed based on the theory of micromagnetism. Results indicate that the temperature dependence of coercivity in the whole temperature range can be well described by the equation Hc = (2K1/Ms) × αKαψ – NeffMs when taking into account the effect of the spin reorientation in the low‐temperature range.Keywords
