Characteristics of the intermediate-field ordered phase of alpha- RuCl3 revealed by magnetic diffraction

ORAL

Abstract

There has been great interest in alpha-RuCl3 as a material that manifests Kitaev terms in the spin Hamiltonian and a possible field-induced quantum spin liquid (QSL) phase by 8 T [1]. Bulk Measurements show that in the in-plane magnetic field causes a transition to an intermediate ordered phase around 6 Tesla [1, 2], preceding the total suppression of magnetic order around 7.3 T. Here we use time-of-flight neutron diffraction to elucidate the nature of intermediate phase and its magnetic order. Our results provide new insights into the dimensionality of the magnetic order and the effective spin-Hamiltonian of the material.
