Change in Unusual Magnetic Properties by Rh Substitution in CeRu^sub 2^Al^sub 10

We have studied the Rh substitution (electron doping) effect in the Kondo semiconductor ..., which orders antiferromagnetically below (T0=27 K), by specific heat C, magnetic susceptibility ..., electrical resistivity ..., and Hall resistivity ...H measurements of Ce(...)... (x=0.12, 0.2, 0.23, 0.34) single crystals. T0 decreases monotonically with an increase in x. In addition, new anomalies occur at T1~6.5 and T2~3.0 K in all the Rh substitution samples. However, T1 and T2 are almost independent of x. The shape of the anomaly at T0 in ...(T) changes with Rh substitution, which implies the reorientation of the ordered moment. These phenomena indicate that the magnetic properties of ... are strongly associated with the number of 4d electrons. (ProQuest: ... denotes formulae/symbols omitted.)
