Magnetic phase diagrams of R2RhIn8 (R = Tb, Dy, Ho, Er and Tm) compounds

Abstract

We have grown and characterized single crystals of R2RhIn8 (R = Tb, Dy, Ho, Er and Tm) compounds crystallizing in the tetragonal Ho2CoGa8-type crystal structure. Their magnetic properties were studied by specific heat and magnetization measurements.

All the investigated compounds order antiferromagnetically with Neel temperatures of 43.6, 25.1, 10.9, 3.8 and 4.1 K, respectively. Magnetic phase diagrams were constructed.
