  Low temperature magnetic and thermal (C_m) properties of the ferromagnetic
(FM) alloys Ce_2.15 (Pd_1-x Rh_x)_1.95 In_0.9 were investigated in order to
explore the possibility for tuning a quantum critical point (QCP) by doping Pd
with Rh. As expected, the magnetic transition observed at T = 4.1K in the
parent alloy decreases with increasing Rh concentration. Nevertheless it splits
into two transitions, the upper being antiferromagnetic (AF) whereas the lower
FM. The AF phase boundary extrapolates to T_N = 0 for x_cr ~ 0.65 whereas the
first order FM transition vanishes at x ~ 0.3. The QC character of the T_N => 0
point arises from the divergent T dependence of the tail of C_m/T observed in
the x = 0.5 and 0.55 alloys, and the tendency to saturation of the maximum of
C_m(T_N)/T as observed in exemplary Ce compounds for T_N => 0. Beyond the
critical concentration the unit cell volume deviates from the Vegard's law in
coincidence with a strong increase of the Kondo temperature.
