Quantum oscillations of bloch point in cylindrical ferromagnetic nanowire: Quasiclassical approach

Year: 2025

Type: article

Abstract: Quantum oscillations of a Bloch point (BP) in the domain wall of a cylindrical ferromagnetic nanowire are investigated using the quasiclassical approximation. The conditions for these oscillations in an external uniform magnetic field are determined. It is shown that quantum oscillations of BP in the domain walls of nickel and iron nanowires can be observed at temperatures of liquid helium. The evolution of the BP wave packet over time is investigated. The characteristic time of its transformation into beats, which form because of superposition of two wave functions with equal amplitudes and close energies and wave numbers, is determined. The train of this wave provides the transfer of BP energy. The obtained results can find practical application in micro - and nanotechnologies based on the quantum properties of BP.
