“We theoretically study the conditions under which an intrinsic spin Nernst effect—a transverse spin current induced by an applied temperature gradient—can occur in a canted-antiferromagnet insulator, such as LaFeO3 and other materials of the same family. … Our paper provides a general derivation of a symmetry-breaking-induced spin Nernst effect, which may open a path to engineering a finite spin Nernst effect in systems where it would otherwise not arise.”
