摘要
The effect of an alternating external magnetic field on spin tunneling is studied for a single axial magnetocrystalline anisotropy model. The model for spin half is solved and the result shows that an alternating field can suppress magnetic tunneling. The probability of tunneling for large spin is obtained with the help of quantum mechanical perturbation theory.
