Abstract:
The ESR spectrum of Gd3+ and Eu2+ monoclinic centers, which substitute for yttrium ions in YAlO3 crystals doped with europium and zirconium, has been investigated. Parameters of the fine structure of these centers are determined. The hyperfine-interaction parameters are determined for the centers with 151Eu isotope, and the hyperfine structure of the centers with 153Eu isotope is discussed.
