ICMCS Seminar - Can the spin textures affect mechanical behaviour in 2D Magnets?

The coupling between the spin degrees of freedom and macroscopic mechanical motions, including striction, shearing, and rotation, has attracted wide interest with applications in actuation, transduction, and information processing. The relationships between spin textures and magnetic fields, currents, and optical stimuli have already been explored in recent 2D materials literature. Experiments so far have studied the mechanical response to spin-texture motion using nanoelectromechanical resonators but lack a theoretical description of the mechanisms at the nano- length scale. In this talk, I will attempt to study spin-mechanical coupling using atomistic and micromagnetic simulations of 2D magnets. First, I will discuss the atomistic spin model results of few-layered MnPS3 and how spin textures can create spin waves that affect mechanical dynamics. Next, I will briefly describe magneto-elastic coupling in micromagnetic simulations of Fe3GaTe2. I will address differences in the mechanical response and properties of the system due to spin texture type and how they can be correlated to experimental results. Finally, I will conclude with the future scope of the work and how spin-mechanical coupling can be used as a strong alternative to current- and laser-based stimuli for spin control in 2D magnets.
