EMR Measurements of Field-Induced Superconductor   lamda-(BETS)2FexGa1-xCl4
  We have performed high-field Electron Magnetic Resonance (EMR) measurements of lamda-(BETS)2FexGa1-xCl4 to clarify the role of Pi- and d-electrons in the paramagnetic (PM) and field-induced superconducting (FISC) phases. We found that this system has a non-negligible Pi-d interaction that is very sensitive to the sample cooling rate. The Pi-d interaction is weaker when the sample is rapidly cooled which might affect its FISC phase. The results of the organic alloy lamda-(BETS)2FexGa1-xCl4 (x=0.6) will be presented in this paper.
