我们表明,在顺磁性固体自旋声子过程的理论必须考虑到声子的相干产生的磁性中心。这种效应应该大大提高纳米顺磁体和分子纳米磁体晶体中的自旋-声子速率。
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.
