摘要：
A new type of effects of quantum tunnelling of magnetization is proposed - tunnelling between equivalent states of a topological soliton in quasi-ID antiferromagnet (AFM). Tunnelling is suppressed in AFM with a half-integer spin of magnetic atoms, due to the effects of destructive quantum interference.
