From in situ EPR tests, we vividly observe a classical redox reaction along with two-electron transfer which only shows one pair of peaks in the cyclic voltammetry curve. WebAug 5, 2024 · A theory developed specifically for materials with strong correlations, known as dynamical mean-field theory (DMFT), predicts that electrons in Sr 2 RuO 4 enhance the coupling between electron momentum and spin (spin-orbit coupling) [ 5, 6 ]. But this predicted enhancement has yet to be tested.
