Ni-vacancy defect in diamond detected by electron spin resonance
Abstract
Trigonal S=1 NOL1/NIRIM5 center has been characterized by electron spin resonance (ESR) in nickel and boron doped diamond grown by the high-pressure high-temperature technique. Hyperfine interaction structure has been detected and attributed to six equivalent carbon sites and one Ni site. Analysis of the ESR parameters strongly suggests assignment of the NOL1/NIRIM5 center to interstitial Ni2+ ion ( 3d8 configuration) situated in the center of a diamond divacancy.
