An anomalous transition in the trimer lattice Ba4Ru3O10*

ORAL

Abstract

4d/5d transitional metal oxides with trimers can often be described by molecular orbitals and host interesting physics including charge density wave, quantum liquid phase, etc. [1, 2]. Our newly synthesized trimer lattice Ba4Ru3O10 features an insulating state that is sensitive to small external DC currents and a sharp transition at T = 100 K that is independent of applied magnetic field up to μ0H = 14 T. This behavior is in sharp contrast to that of its sister compound BaRuO3 that is metallic without any long-range order. The results will be presented and discussed in comparison with other 4d/5d trimer oxides.
