Resumen
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. 37 3 B 1147 1154 Friedman, J.R., Sarachik, M.P., Tejada, J., Ziolo, R., (1996) Phys.
