We report the low-temperature resistance under a magnetic field (μ 0H=0, 5 and 10T) within the temperature range from 1.8 to 300K and low temperature (T=1.9 and 15K) magneto-resistance (μ 0H=0—10T) of heavy electron compounds CeCu 6-x Cd x (x=0.10,0.15,0.20,0.30,0.50). The experiments show that the T max (corresponding to the maximal resistance)of all samples are not observed over 1.8K under zero magnetic field. When a magnetic field is applied, the T max increases with increasing ma...
