Quantum and structural - dimensional phenomena in uniaxial ferromagnetic films and cylindrical nanowires, the magnetic structure of which is characterized by the presence of nanoscale solitons of the "inflection" type in the form of vertical Bloch lines (VBL) and transverse domain walls (DS) is determined. It is assumed that in the band magnetic domain (BMD), which contains a pair of unipolar VBL, low-temperature quantum effects take place: quantum oscillations, tunneling, quantum transitions in the oscillation spectrum, splitting of identical energy levels. It is established that the factor of thermal motion of the transverse DS affects the thermodynamic properties of ferromagnetic nanowires. The critical characteristics of this phenomenon are determined. It is shown that the result of the influence of the DS thermal motion on the process of adiabatic change of the external weak magnetic field is consistent with the fundamental principle of Le Chatelier - Brown self-regulating thermodynamic systems.
