The Electron Spin Resonance spectrum of Gd in the Type II cubic-superconductors LaRu2, CeRu2 and ThRu2 has been observed in both the normal and superconducting regimes. Upon transition from the normal to the superconducting state, the spectra exhibit a a change in line shape AB ratio, b an increase in thermal broadening immediately below TcH, and c a change in g value. Comparison with experiments performed by others, as well as a preliminary interpretation of the data, are presented. Author
