Low-temperature nuclear and magnetic structures of La2O2Fe2OSe2 from x-ray and neutron diffraction measurements

Abstract

This paper describes the low-temperature nuclear and magnetic structures of La 2 O 2 Fe 2 OSe 2 by analysis of x-ray and neutron diffraction data. The material has been demonstrated to order antiferromagnetically at low temperatures, with T N = ∼ 90   K a propagation vector of k = ( 1 2 0 1 2 ) , resulting in a spin arrangement similar to that in FeTe, despite there being no apparent lowering in symmetry of the nuclear structure.
