Neutron scattering studies of the candidate Kitaev material Na<sub>2</sub>PrO<sub>3</sub>

ORAL

Abstract

Na2PrO3 has recently attracted attention as a candidate material to display unconventional magnetism associated with bond-dependent Kitaev interactions between effective spin-1/2 Pr4+ ions [1,2]. Here we report time-of-flight neutron diffraction, and inelastic neutron scattering measurements of the magnetic excitations, and discuss models for the magnetic ground state and spin Hamiltonian.
