Rus, T., H. Wilhelm, O. Stockert, T. Luhmann, N. Caroca-Canales, J. G. Sereni, C. Geibel, and F. Steglich. "Specific heat of CeIn3-xSnx single crystals in the vicinity of the quantum critical point." PHYSICA B-CONDENSED MATTER 359-361 (2005): 62–64.
Abstract: We report on results of low-temperature specific heat experiments on single crystals of the cubic alloy CeIn3-xSnx (x = 0.55,0.60, 0.65, and 0.80). The measurements support three-dimensional critical spin fluctuations in the vicinity of the magnetic instability, i.e. for x(c) approximate to 0.67, where the antiferromagnetic order vanishes.
