Recent experimental and theoretical studies focus on spin-mediated heat currents at interfaces between normal metals and magnetic insulators. We resolve conflicting estimates for the order of magnitude of the spin transfer torque by first-principles calculations. The spin mixing conductance G↑↓ of the interface between silver and the insulating ferrimagnet Yttrium Iron Garnet (YIG) is dominated by its real part and of the order of 1014 Ω−1 m−2, i.e. close to the value for intermetallic interface, which can be explained by a local spin model.

• Antiferromagnetic spintronics (2016, background): “This is enabled by a spin-mixing conductance g↑↓ associated with the Néel order, which is finite even in the case of a compensated magnetization at the interface (Jia et al., 2011; Cheng et al., 2014; Takei et al., 2014), thus allowing for an electronically induced interfacial spin torque τm.”
