Using the circular vibration of surface acoustic waves, a collaborative research group have successfully controlled the magnetization of a ferromagnetic thin film.
Their research was published in the journal
Nature Communications on May 10, 2021.
Essentially, acoustic waves are waves of atomic vibrations in a substance. When the waves propagate across the surface of a material, the vibration becomes circular. This circular motion, known as angular momentum, can help measure rotational motion.
Surface acoustic waves are utilized in bandpass filters in cell phones. The bandpass allows certain frequencies in and keeps unneeded frequencies out. However, storage devices in computers are composed of ferromagnets.

Chirality is the lack of symmetry in matter. Human hands, for example, express chirality. A mirror image of your right hand differs from your left, giving it two distinguishable chiral states.
Chirality is an important issue in a myriad of scientific fields, ranging from high-energy physics to biology.
Within our bodies, some molecules, such as amino acids, show only one chiral state. In other words, they are homo-chiral. It is crucial to understand how this information is transferred and memorized.
