This book presents an experimental investigation of spin-mechanical phenomena in spin-lattice coupled systems. The author demonstrates that the resonant mechanical vibration of a micro magnetic mechanical oscillator changes in response to the magnetization process in the oscillator. The author also investigates a spin-current-induced volume modulation effect in a giant magnetostrictive material. The results presented here accelerate the exploration of cross-correlation effects between spintronics and micromechanics and provide insight into magnetomechanical properties associated with a spin current.

Hiroki Arisawa received his Ph.D. in physics from Tohoku University in 2023. His work focuses on spin-lattice couplings in solids in the field of spin mechanics. He experimentally investigates cross-correlation phenomena between spin angular momentum and mechanical motion via the spin-lattice coupling. During his Ph.D. program, he successfully demonstrated spin mechanical phenomena in several physical systems, such as a micro magnetic mechanical oscillator and a giant magnetostrictive material. He was awarded the Tohoku University President’s Award in 2023.
