Abstract

Electrical resistivity results of Ce (Pt_{1 - x} Ni_x) Ga and CePt (Ga_{1 - y} Al_y) alloys show features at low temperature indicating antiferromagnetic ordering and Kondo behaviour. The variation of Néel temperature with alloy composition is interpreted in terms of a Doniach diagram and the possible existence of a quantum critical point is indicated. Magnetoresistance data are presented and analysed in terms of the Schlottmann formalism.
