Abstract
Crystallographic and magnetic properties of PrRhCu0.5Si1.5 and NdRhCu0 .55Si1.5 have been investigated. Both compounds crystallize in the TbF eSi(2)type structure and display an antiferromagnetic transition at T- N=15 K. Neither of the two display spontaneous magnetization at 4 K. N eutron diffraction patterns reveal simple collinear antiferromagnetic structures with moment values equivalent to 2.39 mu(B) for Nd and 2.19 mu(B) for Pr. The magnetic structures are also described as antiferro magnetic BaAl4 blocks connected by ferromagnetic AIB(2) blocks. The re sults are discussed and compared to the magnetic behavior of RRh2X2 ge rmanides and silicides. (C) 1997 Elsevier Science S.A.
