Electrical devices whose function is based on the spin rather than charge of the electron offer the promise of low-cost, energy efficient practical applications, but using magnetic insulators in such devices are inherently difficult due to limitations in electrical reading mechanisms. Here, the authors report the magnetoresistive detection of perpendicular switching in the insulating ferrimagnetic TbIG using the spin-dependent electron scattering at the TbIG/Cu interface in TbIG/Cu/CoTb multilayers.
