Critical magnetic susceptibility of gadolinium

Abstract

The magnetic suspectibility of a single crystal of high-purity gadolinium has been measured in the critical region with use of AC susceptibility methods. For reduced temperatures t10-3, the data are described by a simple power law of the form X=At-7 with an exponent =1.22(2) and a Curie temperature Tc=293.51 (3) K. For reduced temperatures t10-3, the data cannot be described by a simple power law and indicate the possibility of a crossover to different critical behavior
