Abstract
Abstract Temperature-dependent infrared spectroscopic study of Tb 3+ f–f transitions has been performed for pyrochlore compounds Tb 2 Ti 2 O 7 , (Y 0.99 Tb 0.01 ) 2 Ti 2 O 7 , and (Gd 0.9 Tb 0.1 ) 2 Ti 2 O 7 . The peculiarities of terbium absorption were explained taking into account the presence of inversion symmetry at the rare-earth site. The energies of crystal-field levels for the ground Tb 3+ multiplet were obtained. Spectral anomaly in Tb 2 Ti 2 O 7 observed in the temperature range T
