Magnetic properties of NdRu2Si2 revisited

摘要

Magnetic properties of ternary NdRu2Si2 are analyzed according to resistivity and specific heat studies at very low temperatures. The compound exhibits two magnetic transitions at 9 and 23 K. The latter is the Neel point, whereas the former one was attributed to a change of magnetic ordering from antiferromagnetic to a complex phase with predominant ferromagnetic component. The specific heat measurements reveal an enhancement of electronic specific heat coefficient gamma = 86(1) mJ/mol K-2. The Debye temperature was estimated based on resistivity studies to be 273.1(5) K. (c) 2006 Elsevier Ltd. All rights reserved.
