title: Low temperature magnetic structure of CeRhIn5by neutron diffraction on absorption-optimized samples.
abstract: Two aspects of the ambient pressure magnetic structure of heavy fermion material CeRhIn5have remained under some debate since its discovery: whether the structure is indeed an incommensurate helix or a spin density wave, and what is the precise magnitude of the ordered magnetic moment. By using a single crystal sample optimized for hot neutrons to minimize neutron absorption by Rh and In, here we report an ordered moment of [Formula: see text]. In addition, by using spherical neutron polarimetry measurements on a similar single crystal sample, we have confirmed the helical nature of the magnetic structure, and identified a single chiral domain.
