摘要：

New ESR experiments on Au single crystals doped with Gd impurities yield a positive crystal-field splitting parameter b4=+30.5±1.0 G corresponding to +28.5 × 10-4 cm-1. A fully resolved spectrum is observed. At higher concentrations an exchange-narrowed line appears, produced by interacting impurity spins. Previously published data showed a superposition of a single-ion spectrum and a cluster" line. The positive sign is in agreement with a recent interpretation of lanthanide S states splitting in metals. © 1979 The American Physical Society."
