"Linking Ultrasound and Magnetic Waves with Shear Sound Waves"

Researchers have successfully created a strong coupling between magnons and phonons in a thin film at room temperature, using shear sound waves to link ultrasound and magnetic waves. This breakthrough could lead to the development of hybrid wave-based devices for information processing with minimal losses, potentially opening the door for exciting progress in information and communication technologies. The key element enabling this work was a nano-structured surface acoustic wave resonator, which enhanced shear sound waves and allowed for a strong coupling between surface sound waves and magnets in the resonator.
