Magnetic structure of UnRhIn3n+2 (n = 1, 2) compounds

DOI

The recently discovered compound U2RhIn8 belongs to the family with chemical composition RnTmIn3n+2m, where R is a lanthanide or actinide and T a transition element. The materials grow with a tetragonal unit cell that can be viewed as n-layers of RIn3 stacked sequentially along the c-axis with m-layers of TIn2. This layered structure allows investigating the influence of stacking on the magnetic and superconducting properties within a certain family. With U2RhIn8 and URhIn5 we can study the effect of exchanging the localized 4f-electrons from the Ce-analogous with the more delocalized 5f-electrons. The cubic compound UIn3 orders antiferromagnetically at TN= 88K. U2RhIn8 and URhIn5 order at high temperatures, TN= 117K and 98K, respectively. The propagation vector of UIn3 equals (1/2,1/2,1/2). The same wave vector is found for URhIn5, while our recent experiment on D10 (proposal 5-41-808) revealed for the U2RhIn8 compound a propagation vector of (1/2,1/2,0). This proposal is a continuation of proposal 5-41-808. We like to determine the magnetic moment of the U in U2RhIn8 as well as the temperature evolution of AFM state in U2RhIn8 and URhIn5 to study the influence of the RhIn2-layer.
