Abstract
We consider a ferromagnet whose magnetization is opposite to an applied magnetic field. The rate of quantum nucleation is calculated for a film and is estimated for a bulk solid. The temperature corresponding to the crossover from thermal to quantum nucleation is estimated. The effect may be large enough to be observed in materials with high anisotropy constants.
