Abstract :
[en] We report on the magnetic field evolution of the Neel temperature T-N in the heavy electron system CeIn3-xSnx (x = 0 and 0.3), as determined by specific heat, magnetocaloric effect, and electrical transport measurements. For the stoichiometric compound, T-N is fully suppressed at H-c similar to 65 T, whereas for x = 0.3 the critical field extrapolates to H-c similar to 30 T. An increasing Sommerfeld coefficient gamma, obtained above T-N, as field increases is observed and could be related to the a putative quantum critical point at H-c.
