Abstract: The ESR spectrum of Gd$^{3+}$ and Eu$^{2+}$ monoclinic centers, which substitute for yttrium ions in YAlO$_3$ 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 $^{151}$Eu isotope, and the hyperfine structure of the centers with $^{153}$Eu isotope is discussed.
