  In this work, we investigate the magnetic, heat capacity and electrical
transport properties of Ce0.6La0.4Ge and Ce0.24La0.76Ge compounds. Our results
show that two antiferromagnetic transitions (~ at 4.7 and 2.7 K) exhibited by
Ce0.6La0.4Ge are suppressed below 1.8 K for Ce0.24La0.76Ge. Interestingly, for
Ce0.24La0.76Ge, susceptibility, heat capacity and electrical resistivity vary
with temperature as: T0.75, T0.5 and T1.6 respectively. The observation of such
anomalous temperature variation suggests to the Non-Fermi-liquid (NFL) behavior
due to the presence of disordered 4f spins due to Ce-site dilution. Under the
application of magnetic field, it is noted that a crossover from the NFL to a
magnetic state occurs around 2 Tesla, where, short-range correlations among the
spins is prevalent due to the dominance of coupling between the magnetic
moments via conduction electrons. Magnetoresistance scaling indicates that
behavior of disorder driven NFL state is described by the dynamical mean field
theory of the spin glass quantum critical point.
