摘要：

The electron paramagnetic resonance (EPR) in a single crystal of gadolinium-gallium-garnet has been studied with the aim of understanding the behavior of EPR in systems with large dipolar and small exchange fields, such as encountered in many of the rare-earth based high T(c) superconducting compounds. Only one wide line, arising from Gd3+ has been observed. Its shape at room temperature is analyzed using the Kubo-Toyabe [Magnetic Resonance and Relaxation, edited by R. Blinc (North Holland, Amsterdam, 1967), p. 810] stochastic model for the line shape at static modulation. At low T, the anisotropy in the resonance field is a purely shape effect.
