摘要：

The theory of magnetic tunneling is discussed with an emphasis on antiferromagnets. For antiferromagnets with non-compensated sublattices the crossover from the antiferromagnetic to ferromagnetic quantum dynamics is studied. It is demonstrated that quantum depinning of domain walls must be more pronounced in antiferromagnets than in ferromagnets.
