Title: Magnetically driven maser effect in the resonant dynamics of V-15 molecular nanomagnets

Abstract: Resonant dynamics of magnetic molecules with spin 1/2 ground state, such as V-15, is theoretically studied. In our model calculation, crystals of this molecular nanomagnet are probed by time-dependent magnetic fields, which continuously invert populations of spin states. If the sample is placed in a resonant cavity, relaxation of excited states, via spin-photon interaction, allows for stimulated emission of radiation in the microwave range at resonance.
