Provedeny issledovanija spektrov EPR ionov Er3+, Nd3+ i Ce3+, zameščajuščich iony Y3+ kristalličeskoj rešetke YAlO3. Spektry EPR etich redkozemel'nych ionov opisyvajutsja spinovym gamil'tonianom rombičeskoj simmetrii s effektivnym spinom S=1/2. Na osnovanii analiza uglovych zavisimostej spektrov EPR opredeleny glavnyje značenija g-tenzorov.
EPR spectra Er3+, Nd3+ and Ce3+ ions substituted Y3+ in YAlO3 were observed. The spectra are typical spectra of rhombic centers with effective spin S=1/2. The main values of g-tensor and hyperfine interaction tensors of odd isotopes 167Er, 143Nd and 145Ce were calculated on the basis of analyze of angular dependence of EPR spectra.
