چکیده
In this Letter, we study the spin Nernst effect (SNE) of magnons in nonlinear response regime. We derive formula for magnon current by solving Boltzmann equation and find out that it is described an extended Berry curvature dipole magnons. The SNE expected to occur various N\'eel antiferromagnets without Dzyaloshinskii-Moriya interaction. particular, honeycomb diamond lattice can be controlled strain/pressure.

Magnon Spin Nernst Effect in Antiferromagnets.
We predict that a temperature gradient can induce a magnon-mediated spin Hall response in an antiferromagnet with nontrivial magnon Berry curvature. We develop a linear response theory which gives a general condition for a Hall current to be well defined, even when the thermal Hall response is forbidden by symmetry. We apply our theory to a honeycomb lattice antiferromagnet and discuss a role o...
متن کاملSpin-current order in anisotropic triangular antiferromagnets.
We analyze instabilities of the collinear up-up-down state of a two-dimensional quantum spin-S spatially anisotropic triangular lattice antiferromagnet in a magnetic field. We find, within the large-S approximation, that near the end point of the plateau, the collinear state becomes unstable due to the condensation of two-magnon bound pairs rather than single magnons. The two-magnon instability...
متن کاملThe spin Nernst effect in tungsten
The spin Hall effect allows the generation of spin current when charge current is passed along materials with large spin-orbit coupling. It has been recently predicted that heat current in a nonmagnetic metal can be converted into spin current via a process referred to as the spin Nernst effect. We report the observation of the spin Nernst effect in W. In W/CoFeB/MgO heterostructures, we find c...
متن کاملTowards coherent spin precession in pure-spin current
Non-local spin injection in lateral spin valves generates a pure spin current which is a diffusive flow of spins (i.e. spin angular momentums) with no net charge flow. The diffusive spins lose phase coherency in precession while undergoing frequent collisions and these events lead to a broad distribution of the dwell time in a transport channel between the injector and the detector. Here we sho...
متن کاملSpin-spin correlation lengths of bilayer antiferromagnets
– The spin-spin correlation length and the static structure factor for bilayer antiferromagnets, such as YBa2Cu3O6, are calculated using field theoretical and numerical methods. It is shown that these quantities can be directly measured in neutron scattering experiments using energy integrated two-axis scan despite the strong intensity modulation perpendicular to the layers. Our calculations sh...
