Intrinsic spin Nernst effect of magnons in a noncollinear antiferromagnet

Abstract
This work investigates the intrinsic magnon spin Nernst effect in noncollinear antiferromagnets. The authors introduce a definition of magnon spin current and formulate a linear response theory subject to a temperature gradient. This theory is applied to single-layer potassium iron jarosite KFe3(OH)6(SO4)2, and a measurable spin current response is predicted.
