UNUSUAL HYPERFINE SPECTRA OF Yb(3 plus) IN SCHEELITES,
Abstract
The tetragonal X-band electron paramagnetic resonance spectrum of Yb3+ shows an unusual hyperfine spectrum in the laser host scheelite crystals SrWO4, SrMoO4, PbWO4, and PbMoO4. For these crystals the principal 2I + 1 hyperfine absorption lines of the parallel spectrum do not go continuously into the 2I + 1 lines of the perpendicular spectrum as the angle of the magnetic field is varied from the crystal c-axis. At some angles more than the usual 2I + 1 transitions are observed. This unusual behavior is completely explained by the axial spin-Hamiltonian and the relatively large ratio of B/A for Yb3+ in these crystals. (Author)
