Abstract

We have shown that macroscopic quantum beats of the magnetization can be produced by the standing acoustic wave in molecular magnets. Under the impulsive drive we have demonstrated complete control over the beat structure by adjusting the time interval between the initial state and the application of the sound wave. The optimal condition for the pronounced beat is discussed.
