Abstract
We have studied the charge-density-wave (CDW) state for the superconducting Lu5Ir4Si10 and the antiferromagnetic Er5Ir4Si10 as variables of temperature, magnetic field, and hydrostatic pressure. There is monotonic suppression of the CDW state in Lu5Ir4Si10, while there is complex pressure effect on the CDW states of Er5Ir4Si10. In addition, Er5Ir4Si10 shows negative magnetoresistance at low temperatures, compared with the positive magnetoresistance of Lu5Ir4Si10. The present results suggest that the CDW and magnetism could be coupled because of the presence of f electrons with the local magnetic moment in Er5Ir4Si10.
