Abstract

The response of nanoscale uniaxial magnets to an alternating field is studied by direct numerical calculation. A nontrivial oscillation of the magnetization is found and subsequently analyzed in terms of the nonadiabatic transition due to the time dependent field. A new method to estimate the tunneling gap of the magnet is proposed.
