We report a detailed study of electron longitudinal and transverse spin relaxation times for Li donors in monoisotopic 28Si over the temperature range 4–20 K using continuous wave and pulsed electron paramagnetic resonance. Comparison of the obtained spin-lattice relaxation times for the states of the isolated donor center and lithium complex LiO showed that due to the presence of orbital degeneracy, relaxation is faster for single lithium than for the LiO complexes with the nondegenerate ground state. For the isolated lithium center in silicon the relaxation is well described by Blume-Orbach process, with the parameters of the spin-orbit coupling ~ 1·10-6 meV compare to Orbach process for LiO complex with spin-orbit coupling parameter ~ 1.5·10-2 meV.

Quantitative Calculations

The work I want to describe was started in Bristol in 1959. The purpose was to test theories of spin-lattice relaxation on a system where one could make reasonably quantitative calculations. For this it seemed desirable to study as many aspects of the magnetic properties of one particular system as possible, and to do this both experimentally and theoretically at the same time. The system we chose was cobalt-doped magnesium oxide. This requires some explanation, as at first sight it does not appear to be a particularly simple system. Figure 1 shows how the energy levels of the free cobaltous ion are modified by the crystal field in MgO. The Co 2+ substitutes for Mg 2+ and is surrounded by a regular octahedraon of O 2– ions. The 4 F level splits into three, and these are further split by spin-orbit interaction. The important point is that the lowest level is a Kramers doublet.
