摘要:
Calorimetry experiments under high pressure were used to clarify the interplay between different states such as superconductivity (SC) and antiferromagnetism (AF) in CeRhIn5, spin density wave (SDW) and large moment antiferromagnetism (LMAF) in URu2Si2. Evidences are given on the reentrance of AF under magnetic field in the SC phase of CeRhIn5 up to p(c) = 2.5GPa where the Neel temperature will collapse in the absence of SC. For URu2Si2 measurements up to 10 GPa support strongly the coexistence of SDW and LMAF at high pressures. (c) 2006 Elsevier B.V. All rights reserved.
