Title: Intrinsic spin Nernst effect of magnons in a noncollinear antiferromagnet

Journal Article · · Physical Review Research

We investigate the intrinsic magnon spin current in a noncollinear antiferromagnetic insulator. We introduce a definition of the magnon spin current in a noncollinear antiferromagnet and find that it is in general nonconserved, but for certain symmetries and spin polarizations the averaged effect of nonconserving terms can vanish. We formulate a general linear response theory for magnons in noncollinear antiferromagnets subject to a temperature gradient and analyze the effect of symmetries on the response tensor. We apply this theory to single-layer potassium iron jarosite KFe 3 ( OH ) 6 ( SO 4 ) 2 and predict a measurable spin current response.
