Spin dynamics of the ordered dipolar-octupolar pseudospin-${}^1{/}_2$ pyrochlore Nd${}_2$Zr${}_2$O${}_7$ probed by muon spin relaxation

J. Xu, C. Balz, C. Baines +2

We present a muon spin relaxation study on the Ising pyrochlore Nd${}_2$Zr${}_2$O${}_7$ which develops an "all-in-all-out" magnetic order below 0.4~K. At 20~mK far below the ordering tra…
