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.","lang":"eng"}],"user_id":"16199","title":"Spin-Coupling in Heavily Nitrogen-Doped 4H-SiC","author":[{"last_name":"Savchenko","first_name":"D.V.","full_name":"Savchenko, D.V."},{"full_name":"Pöppl, Andreas","first_name":"Andreas","last_name":"Pöppl"},{"full_name":"Kalabukhova, Ekaterina N.","first_name":"Ekaterina N.","last_name":"Kalabukhova"},{"last_name":"Greulich-Weber","full_name":"Greulich-Weber, Siegmund","first_name":"Siegmund"},{"last_name":"Rauls","full_name":"Rauls, Eva","first_name":"Eva"},{"id":"468","last_name":"Schmidt","full_name":"Schmidt, Wolf Gero","orcid":"0000-0002-2717-5076","first_name":"Wolf Gero"},{"first_name":"Uwe","full_name":"Gerstmann, Uwe","last_name":"Gerstmann","id":"171"}],"publication":"Materials Science Forum","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"}],"status":"public","date_created":"2019-10-15T07:58:04Z","volume":"615-617","publication_status":"published","publication_identifier":{"issn":["1662-9752"]}}
