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

TL;DR

This paper demonstrates how acoustic waves influence macroscopic quantum effects in molecular magnets, revealing sound's role in modulating spin tunneling and generating quantum beats in magnetization.

Contribution

It shows that acoustic waves can significantly affect quantum tunneling and induce quantum beats in molecular magnets, a novel insight into magneto-acoustic interactions.

Findings

Sound strongly affects magnetization steps.

Transverse acoustic waves generate quantum beats.

Magnetization dynamics can be controlled by acoustic waves.

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.
