Stress-induced g shifts of γ7 levels for rare-earth ions

The angular dependence of stress-induced shifts of the gyromagnetic factor g of the Γ7 doublets of Yb3+ and Dy3+ in CaF2 and Er3+ in CeO2 and ThO2 have been measured in electron-paramagnetic-resonance experiments. The observed variation of the angular dependence of the g shifts is explained in terms...
