Abstract
We investigate the quantum tunneling of a domain wall placed in a magn etic field at an arbitrary angle. Using classical soliton solutions, w e derive a domain wall mass which depends on the magnetic field and fi nd that the tunneling time and the crossover temperature strongly depe nd on the direction of the magnetic field. The results are also discus sed at finite temperature. [S0163-1829(98)09641-6].
