Crossover from itinerant to localized magnetic excitations through the metal-insulator transition in NaOsO${}_{\text{3}}$

J. G. Vale, S. Calder, C. Donnerer +8

NaOsO${}_{\text{3}}$ undergoes a metal-insulator transition (MIT) at 410 K, concomitant with the onset of antiferromagnetic order. The excitation spectra have been investigated throu…
