Paramagnetic Resonance of Divalent Holmium in Calcium Fluoride
Abstract
The paramagnetic resonance spectrum of the ground state of divalent holmium in calcium fluoride has been observed at a temperature of 4.3°K and at frequencies of 9 and 27 kMc/sec. The spectrum is isotropic and may be fitted to a spin Hamiltonian with S=12, I=72, A=-0.1307 cm-1, g=-5.912 and GN=+48, where GN is a pseudonuclear g factor. The value of g indicates that the ground state is Γ6. The appearance of a pseudonuclear g factor, which arises because the nearest quartet state has matrix elements with the ground state, permits a determination of the energy separation to the quartet state.
