In this article, the mathematical properties of a Kramers doublet for extrema of the mean $g$ value are extended to monoclinic symmetries.Abstract:
A previous calculation of the mathematical properties of a Kramers doublet for extrema of the mean $g$ value is extended to monoclinic symmetries. The theory is applied to the paramagnetic resonance data for La${\mathrm{F}}_{3}$: ${\mathrm{Yb}}^{3+}$. These data are shown to be consistent with a ${\mathrm{Yb}}^{3+}$ site of ${\mathrm{C}}_{2v}$ point symmetry.read more

Low-symmetry effects in electron paramagnetic resonance
J R Pilbrow,M R Lowrey +1 more
TL;DR: The role of excited-state orbitals, under the influence of low-symmetry fields, is largely responsible for the different orientations of the principal directions of the various interactions experienced by a paramagnetic ion as discussed by the authors.

EPR Investigations of Er3+, Yb3+, and Gd3+ in Zircon‐Structure Silicates
TL;DR: In this article, the EPR spectra of Er3+, Yb3+, and Gd3+ have been observed in the host single crystals ZrSiO4, HfSiO 4, and Th SiO4 which were grown by a flux-gradient technique.

An electron paramagnetic resonance study of Er3+ in Bi4Ge3O12 single crystals
D. Bravo,F. J. López +1 more
TL;DR: In this paper, the X-band electron paramagnetic resonance study of Er•doped Bi4Ge3O12 single crystals at 5 K is reported, and the spectra have been attributed to Er3+ ions in the Bi3+ site, confirming the assumed trigonal site symmetry.

Magnetic properties of a Kramers doublet. An univocal bridge between experimental results and theoretical predictions
TL;DR: This procedure is extended to find a spin-Hamiltonian suitable for describing the magnetic behavior of a pair of weakly coupled Kramers systems in the multispin scheme when the interaction between the two moieties as well as the individual Zeeman interaction are small enough as compared with ligand field splitting.
