| Abstract: | The YAlO3: Tm3+ single crystal has been studied on a wide-band EPR spectrometer. The EPR spectra of Tm3+ ions in the frequency range of 90–160 GHz have been detected for the first time. It has been confirmed that thulium ions substitute the position of Y3+ in the crystal lattice. The detected spectra have been described with the use of a spin Hamiltonian with the effective spin S = 1/2. A comparative analysis of the orientation of the magnetic axes of the Tm3+ paramagnetic center with earlier data on other rare-earth ions has been performed. |
