Abstract
We report transmission electron-spin-resonance and EPR measurements on unbottlenecked :Er dilute alloys. We have derived theoretical expressions for the effects of the exchange and crystal-field interactions on the properties of the resonances. A computer fit of these expressions to the data yields the crystal-field parameters, the sign, magnitude, and a measure of the dependence of the exchange interaction, and the spin-flip scattering cross section and free-ion value of the Er impurities.
