Abstract

The slightly curved paramagnetic background (due to Brillouin dependence) of the paramagnetic light rare earth ions in 123 superconductors mixes below T c with reversible magnetization, which hinders evaluation of the associated thermodynamic characteristics. We propose a method how to determine the effective number of magnetons per ion, the principal parameter of the Brillouin function course, even in materials with pores, with unknown or varying density and/or the local composition. The method was tested on various types of compounds containing Gd ions, like pure Gd-211, tetragonal Gd-123, (Y,Gd)-123, and (Nd,Eu,Gd)-123 and on orthorhombic (oxygenated) Gd-123 and (Nd,Eu,Gd)-123.
