Xiaojia Wang Publishes New Research in Science Advances

In a recent Science Advances paper, ME Associate Professor Xiaojia Wang and members of her research group, the Micro/Nanoscale Thermal Transport Laboratory, along with and collaborators Professors Jian-Ping Wang and Randall Victora from ECE explore the spin-strain coupling in a technologically important magnetic material system. Dr. Wang’s group led the experimental efforts of utilizing an ultrafast laser to excite and detect, for the first time, an extremely high resonance frequency (~60 GHz) between the spin precession and acoustic strain.

Results of this work pave the way for manipulating magnetization switching using acoustic strain waves for developing non-volatile random-access memory (RAM) for future data storage and computing devices.
