摘要翻译：
我们研究了磁性分子晶体中的磁弹性效应。推导了自旋与声的耦合运动方程，证明了强共振磁声耦合的可能性。得到了体声波和声表面波在线性声和自旋激励作用下的色散规律。我们表明超声可以产生自旋能级的反布居。或者，自旋能级的反向布居数的衰变可以产生超声波。论证了磁化孤波伴随弹性扭转的可能性。

英文摘要：
  We study magneto-elastic effects in crystals of magnetic molecules. Coupled equations of motion for spins and sound are derived and the possibility of strong resonant magneto-acoustic coupling is demonstrated. Dispersion laws for interacting linear sound and spin excitations are obtained for bulk and surface acoustic waves. We show that ultrasound can generate inverse population of spin levels. Alternatively, the decay of the inverse population of spin levels can generate ultrasound. Possibility of solitary waves of the magnetization accompanied by the elastic twists is demonstrated.
