The spin mixing conductance g↑↓ of a ferromagnetic and a nonmagnetic (NM) layer characterizes the transport efficiency of spin current through the interface. Exploration of the relationship between g↑↓ and structural parameters such as the la

We investigate spin-orbit torques in prototypical Pt-based spintronic devices. We find that, in Pt/Ni and Pt/Fe bilayers, the dampinglike torque efficiency depends on the thickness of the Pt layer. We also find that the dampinglike torque efficiency

We report intrinsic spin decay length of an antiferromagnetic insulator. We found that at an antiferromagnetic/ferromagnetic interface, a spin current generated by spin pumping is strongly suppressed by two-magnon scattering. By eliminating the two-m

We report the observation of spin transport through antiferromagnetic insulators using spin pumping driven by short-wavelength magnons. The short-wavelength magnons are excited by parametric pumping in a $\mathrm{Pt}/\mathrm{NiO}/{\mathrm{Y}}_{3}{\ma

We report a quantitative study of two-magnon scattering in ${\mathrm{Ni}}_{81}{\mathrm{Fe}}_{19}$/NiO bilayers with various NiO thicknesses ${d}_{\mathrm{NiO}}$. We found that the magnetic damping of the ${\mathrm{Ni}}_{81}{\mathrm{Fe}}_{19}$/NiO bil

Characteristic size of magnetic domains in Fe films deposited on NiO layers was measured by spin-polarized low-energy electron microscopy. Our observation results and statistical analysis revealed the increase of magnetic domain sizes with the Fe-thi
