Anomalous charge density wave transition in superconducting Lu5Rh4Si10

We report the investigations of specific heat, thermal conductivity and the rmoelectric power on the intermetallic Lu5Rh4Si10 at temperatures above the superconducting transition T-c similar to 3.9 K. All measured results cons istently show anomalous peaks at its charge density wave (CDW) transition T -p similar to 147 K. The observed peaks in the specific heat and thermal co nductivity are significantly large, in contrast to conventional CDW systems . It suggests that possibly strong interchain interactions manifest the CDW transition in this material. (C) 2001 Elsevier Science B.V. All rights res erved.
