text: In non-annealed 6H-SiC samples that were electron irradiated at room
temperature, a new EPR signal due to a S=1 defect center with exceptionally large
zero-field splitting (D = +652•10-4 cm-1) has been observed under illumination.
A positive sign of D demonstrates that the spin-orbit contribution to the zero-field
splitting exceeds by far that of the spin-spin interaction. A principal axis of
the fine structure tilted by 59° against the crystal c-axis as well as the exceptionally
high zero-field splitting D can be qualitatively understood by the occurrence
of additional close-lying defect levels in defect clusters resulting in comparatively
large second-order spin-orbit coup¬ling. A tentative assignment to vacancy clusters
is supported by the observed annealing behavior.

text: EPR and ESE in nitrogen doped 4H- and 6H-SiC show besides the well
known triplet lines of 14N on quasi-cubic (Nc,k) and hexagonal (Nc,h) sites additional
lines (Nx) of comparatively low intensity providing half the hf splitting of Nc,k.
Frequently re-interpreted as spin-forbid¬den lines, arising from Nc,k pairs and
triads or resulting from hopping conductivity, only re¬cent¬ly the theoretical
calculation of the corresponding g-tensors lead to a tentative model of distant
NC donor pairs on inequivalent lattice sites which are coupled to S = 1 assuming
a fine-struc¬ture splitting too small to be observed in the EPR and ESE experiments.
In this work, we pre¬sent ESE nutation measurements confirming S = 1 for the Nx
center. Analysing the nutation frequencies in comparison with that of the Nc,k
(S = 1/2) spectrum as well as the line width of ESE and EPR spectra we obtain
a rough estimate between 5104 cm-1 and 50104 cm-1 for the fine-structure splitting
demonstrating efficient spin-coupling between nitrogen donors in 4H-SiC.
