Relationship between spinons and magnetic fields in a fractionalized
state
The 4d-electron trimer lattice Ba4Nb1-xRu3+xO12 is believed to feature a universal heavy spinon Fermi surface that underpins both a quantum spin liquid (QSL) and an adjacent heavy-fermion strange metal (HFSM), depending on Nb content; the itinerant spinons as heat carriers render the charge-insulating QSL a much better thermal conductor than …
