摘要：

Quantum oscillations in small magnetic particles, induced by external magnetic field, are considered. It is shown that, due to tunneling of the total magnetization M0, the ground-state energy of the system oscillates as a function of the external-magnetic-field strength with period deltaH = (mu/M0)H(c) (mu is the magnetic moment; H(c) is the coercive field). In small anisotropic antiferromagnetic particles, the magnetic field enhances the Neel-vector tunneling rate and generates oscillations in the soliton rest energy.
