Abstract : The electron-spin resonance of GD, Dy, and Er has been observed in dilute Al-based alloys. From the temperature-dependent linewidth and the sign of the g shift, a value of the exchange integral was extracted for Al:Dy and Al:Er. The more concentrated Al:Gd alloys exhibited a strong magnetic-resonance bottleneck, which was partially opened by (1) reduction of the Gd concentration and (2) by introducing a third element. The exchange integral was found for Al:Gd, and values were obtained for the spin-lattice relaxation rate of the conduction electrons from band effects, the Gd impurities themselves, and the third elements (Ag, Au).
