| In this paper we present the results of ESR and photo-ESR measurements on YAlO3(YAP) single crystals and powder samples doped purposely with about 1 at.% Nd3+ and undoped crystals in which Er3+ was observed as residual dopant. The ESR measurements were carried out at X-band spectrometer in 4-300 K temperature range. The photo-ESR was performed at 5 K using a mercury arc lamp. For the Nd3+ doped crystals the intensity of ESR signal decreased about 2 times during illumination conditions. Moreover, the calculations of the g tensor and A hyperfine structure parameters for Nd3+ and Er3+ were carried out. |
