A combination of novel technological and fundamental physics prospects has sparked a huge interest in pure spin transport in magnets, starting with ferromagnets and spreading to antiferro- and ferrimagnets. We present a theoretical study of spin transport across a ferrimagnet-nonmagnetic conductor interface, when a magnetic eigenmode is driven into a coherent state. The obtained spin current expression includes intra- as well as cross-sublattice terms, both of which are essential for a… Expand

Spin Splitting Induced in a Superconductor by an Antiferromagnetic Insulator.
It is found that an antiferromagnetic insulator with effectively uncompensated interface induces a large, disorder-resistant spin splitting in the adjacent superconductor, avoiding the detrimental, parasitic effects of ferromagnets employed to this end. Expand

Spin pumping and spin-transfer torques in antiferromagnets.
By calculating how electrons scatter off a normal metal-antiferromagnetic interface, pumped spin and staggered spin currents are derived in terms of the staggered field, the magnetization, and their rates of change. Expand
Origin of the spin Seebeck effect in compensated ferrimagnets
It is demonstrated that higher-energy exchange magnons play a key role in the SSE, which is caused by thermally excited spin dynamics that are converted to a voltage by the inverse spin Hall effect at the interface to a heavy metal contact. Expand
Super-Poissonian Shot Noise of Squeezed-Magnon Mediated Spin Transport.
It is found that the shot noise of the spin current traversing the F|N interface when F is subjected to a coherent microwave drive is frequency independent up to the drive frequency, and increases linearly with frequency thereafter. Expand
Enhanced Spin Conductance of a Thin-Film Insulating Antiferromagnet.

Thermal Spin Dynamics of Yttrium Iron Garnet.
The method of atomistic spin dynamics is used to study the temperature evolution of the full spin wave spectrum, in quantitative agreement with neutron scattering experiments, and the antiferromagnetic or optical mode is found to suppress the spin Seebeck effect at room temperature and beyond due to thermally pumped spin currents with opposite polarization to the ferromagnetic mode.
