We report neutron diffraction experiments performed in the tetragonal antiferromagnetic
heavy fermion system CeRhIn 5− x Sn x in its (x, T) phase diagram up to the vicinity of the
critical concentration xc≈ 0.40, where long range magnetic order is suppressed. The
propagation vector of the magnetic structure is found to be k IC=(1/2, 1/2, kl) with kl
increasing from kl= 0.298 to kl= 0.410 when x increases from x= 0 to x= 0.26. Surprisingly,
for x= 0.30, the order has changed drastically and a commensurate antiferromagnetism with …

We report neutron diffraction experiments performed in the tetragonal antiferromagnetic heavy fermion system in its phase diagram up to the vicinity of the critical concentration , where long range magnetic order is suppressed. The propagation vector of the magnetic structure is found to be with increasing from to when increases from to . Surprisingly, for , the order has changed drastically and a commensurate antiferromagnetism with is found. This concentration is located in the proximity of the quantum critical point where superconductivity is expected.
