Abstract

Using an X-band EPR spectrometer and a submillimeter EPR spectrometer, Y3Al5O12 (YAG), (Y0.9Lu0.1)3Al5O12 (YLuAG) crystals with erbium and YAG with iron were investigated. In YAG:Er crystals the resonance transitions between ground and the first excited doublets in the frequency range 580-750 GHz were observed. The energy interval to the first excited Stark level is measured and the direction of the axes of the g-tensor of the excited doublet is specified. The field-frequency and angular dependences of these transitions are measured and theoretically calculated. In the YAG:Fe crystal a non-Kramers ion was detected in the frequency range 112-150 GHz. It was concluded that resonant transitions between the |+2⟩ ↔ |−2⟩ states of the Fe2+ ion in the tetrahedral environment are observed.
