Nontrivial resonance of nanoscale uniaxial magnets to alternating field
How nanoscale uniaxial magnets respond to an alternating field is studied by direct numerical calculation. A nontrivial oscillation of the magnetization is found, which is analyzed in terms of the non-adiabatic transition due to the time dependent field. A new method to estimate the tunneling gap of the magnet is proposed.
