Abstract and subjects
Measurements of magnetic susceptibility, specific heat, and electrical resistivity have been performed on single crystals of
CeRhIn

. The antiferromagnetic order at
T
N

3.8
K
that occurs in the heavy-fermion pressure-induced superconductor CeRhIn
5 is suppressed by Sn substitution at a critical concentration

. Non-Fermi liquid behavior is observed in the vicinity of

c
suggesting an antiferromagnetic quantum critical point. The evolution of the antiferromagnetic order, a Schottky anomaly centered around 3
K attributed to short-range magnetic correlations, and non-Fermi liquid behavior in

indicates a localized/itinerant crossover of the Ce f electrons, similar to the one that occurs in CeRhIn
5 at applied pressure.
