Inelastic neutron scattering study of 5d4 chain compound La2ZnRuO6
Recently, a strong interest has arisen from the 4d and 5d transition metals. Indeed, spin-orbit coupling and electronic correlations naturally combine in those materials, which in turn may host new phases of matter. According to recent theoretical work, the d4 electronic configuration is quite interesting as super-exchange opposes to spin-orbit coupling, yielding a phase transition from nonmagnetic atomic singlets to novel and unexplored magnetic phases. An excellent candidate to test this physics is La2ZnRuO6, a double perovskite with ordered B-site where the Ru4+ is in the 4d4 configuration. Owing to our preliminary characterizations, this particular material could be at the border between those phases. We propose an INS study of this candidate material on PANTHER.
