Abstract

A polarized neutron diffraction experiment gives direct evidence for a charge order in the extremely low-carrier system Yb₄As₃. Inelastic neutron scattering experiments on Yb₄As₃ revealed the existence of low-energy spin excitations that are characteristic of a one-dimensional antiferromagnetic coupling at low temperatures. The results indicate that the one-dimensional arrangement of Yb³⁺ ions caused by the charge order plays a main role for the heavy-electron behavior in Yb₄As₃.
