Collaborative MRSEC Research Results in Nano Letters Cover Article Last Month

Wisconsin MRSEC research groups (Xiao, Wang, Ping) have made significant progress in understanding and engineering the spin-mechanical coupling properties of two-dimensional materials CrSBr, an air-stable 2D magnet. Using nano-opto-electro-mechanical systems (NOEMS), they have observed the magnetostriction strength in 2D CrSBr is a factor of 10 times larger than that in yttrium iron garnet (YIG), a state-of-the-art quantum material for hybrid quantum magnonics. Moreover, for the first time, we have demonstrated the magnetostriction effect can be controlled by gate-induced strain, with as striking as 50% amplitude tuning in the magnetoelastic coupling strength.

“These results reveal large spin-mechanical coupling in atomically thin CrSBr, which can potentially lead to long-sought efficient quantum transduction using cavity magnomechanics schemes. Such nontrivial coupling may also lead to efficient magnon generation, which is important for on-chip spintronics,” says Prof. Jun Xiao, the corresponding author of this work.
