A high-quality crystalline, thulium iron garnet (Tm3Fe5O13, TmIG) fabricated by on-axis radio frequency (RF)-magnetron sputtering was reported on recently published paper from npj Spintronics. Combining with a large spin Hall conductivity metal, platinum (Pt), the magnetization can be electrically detected, even though TmIG is an insulator. On-axis sputtering method is an industry-compatible technology to provide better productivity without geometry limitation. This is the first paper to report spin-orbit torque switching by applying TmIG/Pt heterostructure using on-axis sputtering technique.
This work was collaborated by Prof. Saroj Dash’s group, from Chalmers University of Technology and researchers from Japan, South Korea and Indonesia.
