Notes:
Analysis of the leading nonlinear term of the susceptibility χ3(T) of the singlet-ground-state heavy-fermion superconductor UPd2Al3 shows evidence for a jump at TN and a "third-order'' Curie–Weiss type behavior at higher temperatures, inferring quadrupolar or magnetoelastic interactions. These effects are closely related to quadrupolar correlations observed in measurements of the nonlinear susceptibility and calculated in a crystal-electric-field approach for the singlet-ground-state systems URu2Si2 and PrNi5 .
