Macroscopic quantum effects generated by the acoustic wave in a molecular magnet

Abstract

We have shown that the size of the magnetization step due to resonant spin tunneling in a molecular magnet can be strongly affected by sound. The transverse acoustic wave can also generate macroscopic quantum beats of the magnetization during the field sweep.
