| Abstract: | We report transport and calorimetric measurements at high pressure on CeIn 3 crystals grown from a flux of excess indium. This technique allows the growth of large crystals which are suitable for techniques which require large sample volumes. Measurements were carried out in a Bridgman cell which allowed pressures of up to 100 kbars to be reached. The results obtained for the antiferromagnetic and superconducting phase diagram are very similar to previous results obtained on small crystals and in hydrostatic cells. We also find a well defined Quantum Critical Point and Non Fermi-Liquid behaviour of the normal state resistivity. We report the first measurements of the upper critical field and of the specific heat at high pressure on this compound. |
