The electron spin resonance study of heavily nitrogen doped 6H SiC crystals
Original language description
The magnetic and electronic properties of heavily doped n-type 6H SiC samples with a nitrogen concentration of 1019 and 4 x 1019cm-3 were studied with electron spin resonance (ESR) at 5?150 K. The observed ESR line with a Dysonian lineshape was attributed to the conduction electrons (CE). The CE ESR (CESR) line was fitted by Lorentzian (insulating phase) (T<40 K) and by Dysonian lineshape (metallic phase) above 40 K, demonstrating that Mott insulator-metal (IM) transition takes place at 40 K, accompanied by significant change in the microwave conductivity. The temperature dependence of CESR linewidth follows the linear Korringa law below 40 K, caused by the coupling of the localized electrons (LE) and CE, and is described by the exponential law above 40K related to the direct relaxation of the LE magnetic moments via excited levels driven by the exchange interaction of LE with CE.n
