Description

The compound CeRh3B2 is known to order magnetically with an unusually high Curie temperature (T/sub C/) of 115 K and a low saturation moment of about 0.4μ/sub B/. We have studied the magnetic behavior of the system CeRh3(B/sub 1-//sub x/Si/sub x/)2 (0 ≤ x ≤ 0.5). It is observed that on partial replacement of B by Si an anisotropic lattice expansion takes place and the magnetic moment per Ce ion increases to more than 0.8μ/sub B/ but at the same time T/sub C/ shows a remarkable decrease by an order of magnitude to 16 K for CeRh3BSi. These results suggest that the anomalous behavior of CeRh3B2 arises because of the Ce 4f hybridization with the neighboring ligands
