摘要：
Tunneling through a vertical Bloch line (BL) defect in the domain wall of a cylindrical magnetic domain is considered. It is shown that the BL tunneling probability and the corresponding crossover temperature are determined by the vibrational spectrum of the domain. The parameters characterizing this effect are estimated for a state of the domain close to the elliptical instability state.
