WebThe competition and cooperation between spin-orbit coupling (SOC) and electron correlations induces novel phenomena in 4d and 5d transition metal oxides such as spin-orbit-assisted Mott insulators, topological phases, and spin liquids [1]. The pyrochlore iridates A2Ir2O7 (A ¼ Pr, Nd, Y, etc.) are an ideal system to study these phenomena WebJul 20, 2024 · 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.
