Abstract
The influence of the spin reorientation phenomenon on the nucleation f ield of NdFeB magnets is analyzed based on the theory of micromagnetis m. Results indicate that the temperature dependence of coercivity in t he whole temperature range can be well described by the equation H-c = (2K(1)/M(s)) x alpha(K) alpha(psi) - N(eff)M(s) when taking into acco unt the effect of the spin reorientation in the low-temperature range.
