Spintronics offers promising routes for efficient memory, logic, andcomputing technologies. The central challenge in spintronics is electricallymanipulating and detecting magnetic states in devices. The electrical controlof magnetization via spin-orbit torques is effective in both conducting andinsulating magnetic layers. However, the electrical readout of magnetization inthe latter is inherently difficult, limiting its use in practical applications.Here, we demonstrate magnetoresistive detection of perpendicular magnetizationreversal in an electrically insulating ferrimagnet, terbium iron garnet (TbIG).To do so, we use TbIG|Cu|TbCo, where TbCo is a conducting ferrimagnet andserves as the reference layer, and Cu is a nonmagnetic spacer. Currentinjection through Cu|TbCo allows us to detect the magnetization reversal ofTbIG with a simple resistance readout during an external magnetic field sweep.By examining the effect of measurement temperature, TbCo composition, and Cuthickness on the sign and amplitude of the magnetoresistance, we conclude thatthe spin-dependent electron scattering at the TbIG|Cu interface is theunderlying cause. Technologically-feasible magnetoresistive detection ofperpendicular switching in a ferrimagnetic garnet is a breakthrough, as itopens broad avenues for novel insulating spintronic devices and concepts.
