Title: Localization effects in Ce{sub 1.8}Nd{sub 1.2}Al

Electrical resistivity in the presence of magnetic fields for Ce{sub 1.8}Nd{sub 1.2}Al is reported. 40% Nd doped Ce{sub 3}Al is speculated to be at the verge of a Quantum Critical Point (nearness to QCP). A simple look at the resistivity shows no signatures of any structural or Kondo like behavior and RKKY interaction completely dominates the Kondo ordering. This composition is also expected to be near a ferromagnetic instability. However, there is no visible resistivity anomaly. The value of the resistivity is in the range of low end of semiconductor but the behavior is like a metallic one. This indicates the presence of localization terms. The resistivity in various fields is fitted accordingly and the results are indicative towards such a scenario. Magnetoresistance (MR) in all fields is positive and corroborates the results.
