Quantum tunneling by magnetostatic interaction of fine ferroparticles (clusters)

This paper considers macroscopic quantum tunneling of magnetization in the system of fine ferroparticles (clusters) with account of their magnetostatic interaction. This effect is found to be fully determined only by the magnetostatic interaction of particles. It is shown that the quantum tunneling...

Description
Summary:This paper considers macroscopic quantum tunneling of magnetization in the system of fine ferroparticles (clusters) with account of their magnetostatic interaction. This effect is found to be fully determined only by the magnetostatic interaction of particles. It is shown that the quantum tunneling effect results in the resonance absorption peak of a nonuniform ac magnetic field.
