Abstract

We report magnetic susceptibility, electrical resistivity, and low-temperature heat capacity data for La-doped Ce_mRh_nIn_3m+2n (m = 1, 2; n = 0,1) antiferromagnetic heavy-fermion compounds. Antiferromagnetism is smoothly suppressed by La doping and T_N extrapolates to zero at x_c≈40% for the m = 1, 2; n = 1 tetragonal variants and at x_c≈65% for cubic CeIn₃. Our results are discussed in terms of the quasi-two-dimensional character of CeRhIn₅ and Ce₂RhIn₈ as compared to their cubic relative CeIn₃. For CeRhIn₅, short-range magnetic order and non-Fermi-liquid behavior are observed for higher La concentration.
