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 BA for Yb3 in these crystals. Author
