Abstract
Abstract We present an investigation of CeTMAl phase diagrams with TMRu, Pd, Pt and Au. Several new compounds have been characterized by measurements of the electrical resistivity ϱ ( T ), the do susceptibility χ ( T ) and, in some cases, the specific heat C ( T ). We find that in the compounds with TMRu, the hybridization strength between 4f and conduction electrons is strong, leading in most compounds to an intermediate valent (IV) state. By contrast, most of the investigated compounds with TMPd, Pt and Au order magnetically indicating a much weaker hybridization strength. However, some of the Pt and especially Pd compounds are very near to the crossover from the magnetic to the non-magnetic regime as deduced from a Kondo-type maximum in the resistivity and a large electronic specific heat at low temperatures.
