Аннотация
The circularly polarized luminescence spectra of Y3Al5O12-Tb and Y3Al5O12-Ho garnets are analyzed in the wavelength ranges of the 5 D 4 → 7 F 5 transition in the Tb3+ ion and the 5 S 2 → 5 I 8 transition in the Ho3+ ion. It is found that the intensities of the orthogonal circularly polarized components of the series of luminescence lines attributed to the studied garnets differ substantially. The results obtained are interpreted in terms of the mixing of the Tb3+ and Ho3+ electronic states in an external magnetic field.
