Direct Evidence for the all-in/all-out Magnetic Structure in the Pyrochlore Iridates from Muon Spin Relaxation

Abstract

An analysis of the experimentally measured spontaneous spin procession of muons in the pryochlore iridates R2Ir2O7 (R = Lanthanide, Y) is presented here. It is shown through a novel approach incorporating both probabilistic and ab-initio modeling techniques that the experimentally observed results are consistent only with a magnetically ordered Ir4+ sublattice with the so-called 'all-in/all-out' magnetic structure, and that the electronic state of the Ir4+ is best described by the Jeff = 1/2 model in several member compounds. This approach also demonstrates how such simple order is not present on the rare-earth sublattice, specifically when R=Nd.
