Magnetic ordering in UCu2Si2 at high pressure

Physica B Condensed Matter (Impact Factor: 1.32). 04/2008; 403(5-9):940-942. DOI: 10.1016/j.physb.2007.10.279


We have performed resistivity measurements as a function of applied pressure to 2.0 GPa on a single crystal of UCu2Si2. We find that the ambient pressure magnetic ordering temperature of 100 K, and the low-temperature ordering at 50 K, both decrease gradually in a manner consistent with itinerant magnetism. The results will be compared to previous measurements on UCu2Ge2.
