Coupled Spin-Charge-Phonon Fluctuation in the All-In/All-Out Antiferromagnet Cd$_2$Os$_2$O$_7$

Akihiro Koda, Hana Hirose, Masanori Miyazaki, Hirotaka Okabe et autres

We report on a novel spin-charge fluctuation in the all-in-all-out pyrochlore magnet Cd$_2$Os$_2$O$_7$, where the spin fluctuation is driven by the conduction of thermally excited electrons/holes and associated fluctuation of Os valence. The fluctuation exhibits an activation energy significantly greater than the …

Lifshitz metal–insulator transition induced by the all-in/all-out magnetic order in the pyrochlore oxide Cd2Os2O7

Zenji Hiroi, J. Yamaura, Taku Hirose, Ikuo Nagashima et autres

We investigate the metal-insulator transition (MIT) of the osmium pyrochlore oxide Cd 2 Os 2 O 7 through transport and magnetization measurements.The MIT and a magnetic transition to the all-in/all-out (AIAO) order occur simultaneously at 227 K.We propose a mechanism based on …
