Spin-orbit-driven magnetic structure and excitation in the 5d pyrochlore Cd2Os2O7

Autor: S. Calder, J. G. Vale, N. A. Bogdanov, X. Liu, C. Donnerer, M. H. Upton, D. Casa, A. H. Said, M. D. Lumsden, Z. Zhao, J. -Q. Yan, D. Mandrus, S. Nishimoto, J. van den Brink, J. P. Hill, D. F. McMorrow, A. D. Christianson

Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-8 (2016)

Strong electronic correlations in 5d materials such as osmates may combine with spin-orbit coupling to yield novel order. Here, the authors demonstrate how spin-orbit coupling in pyrochlore Cd2Os2O7generates magnetic order and excitations associated
