Abstract

The magnetism of PrCu2Si2 is known to be unique in the sense that the enhancement of the Nè el temperature TN with respect to the de Gennes scaled value is the largest in this rare-earth (RE) series. Here, we report that TN shows a tendency to increase with external pressure, in sharp contrast to the behaviour noted earlier by positive chemical pressure generated by the substitution of isoelectronic ions for Pr. Possible explanations for this puzzling observation are mentioned.
