Query: Intrinsic Magnon Nernst Effects in Pyrochlore Iridate Thin Films   We theoretically study the magnon spin thermal transport using a strong
coupling approach in pyrochlore iridate trilayer thin films grown along the
[111] direction. As a result of the Dzyaloshinskii-Moriya interaction (DMI),
the spin configuration of the ground state is an all-in/all-out ordering on
neighboring tetrahedra of the pyrochlore lattice. In such a state, the system
has an inversion symmetry and a Nernst-type thermal spin current response is
well defined. We calculate the temperature dependence of the magnon Nernst
response with respect to the magnon band topology controlled by the spin-orbit
coupling parameters and observe topologically protected chiral edge modes over
a range of parameters. Our study complements prior work on the magnon thermal
Hall effect in thin-film pyrochlore iridates and suggests that the [111] grown
thin-film pyrochlore iridates are a promising candidate for thermal spin
transport and spin caloritronic devices.
