Low temperature magnetic phase diagram of the cubic non-Fermi liquid system CeIn(3-x)Snx
Abstract
In this paper we report a comprehensive study of the magnetic susceptibility (), resistivity (), and specific heat (CP), down to 0.5 K of the cubic CeIn(3-x)Snx alloy. The ground state of this system evolves from antiferromagnetic (AF) in CeIn3(TN=10.2 K) to intermediate-valent in CeSn3, and represents the first example of a Ce-lattice cubic non-Fermi liquid (NFL) system where TN(x) can be traced down to T=0 over more than a decade of temperature. Our results indicate that the disappearance of the AF state occurs near xc ~ 0.7, although already at x ~ 0.4 significant modifications of the magnetic ground state are observed. Between these concentrations, clear NFL signatures are observed, such as (T)≈ 0 + A Tn (with n<1.5) and CP(T) -T ln(T) dependencies. Within the ordered phase a first order phase transition occurs for 0.25 < x < 0.5. With larger Sn doping, different weak (T) dependencies are observed at low temperatures between x=1 and x=3 while CP/T shows only a weak temperature dependence.
