It is shown that in the external magnetic field directed along the plane of the DS, there is a tunneling through the energy barrier formed by potential wells of solitons, both of individual small sections of longitudinal and vertical planes as a whole. Moreover, in the latter case, stronger magnetic fields are required. This quantum effect is essentially superficial, and disappears when passing to bulk materials. In the case of strong magnetic fields, the energy of which significantly exceeds the energy of quantum oscillations of vertical drones, there is a classical (not quantum) exchange interaction of two solitons. located in the domain wall of the strip magnetic domain formed in a uniaxial ferromagnetic film. It is shown that this effect takes place due to the account of quantum oscillations of vertical Bloch lines excited by an external magnetic field in the subhellium temperature range. The conditions for the realization of the above phenomenon are formulated, which can be extended to other types of topological solitons. A formalism for determining the thermodynamic characteristics of magnetic nanodromes containing a domain wall is constructed. Product Description popup.authors Bespalov Serhii A. Vlaikov Heorhii H.
