Phonon Superradiance and Phonon Laser Effect in Nanomagnets

E. M. Chudnovsky, D. A. Garanin
2004 Physical Review Letters  
We show that the theory of spin-phonon processes in paramagnetic solids must take into account the coherent generation of phonons by the magnetic centers. This effect should drastically enhance spin-phonon rates in nanoscale paramagnets and in crystals of molecular nanomagnets.
