摘要: Experimentally observed electron paramagnetic resonance (EPR) spectra of highly oriented pyrolytic graphite samples can be considered as a sum three signals coming from two adjacent faces and crystal edges. Contributions analyzed analytically by Dyson’s theory based on an infinite flat conductive plate, while the contribution edges is not described this theory. Overlapping these makes it difficult to get useful information about sample observed. Implementation two-dimensional spectral-spatial imaging technique proved helpful solve problem. It permits characterization EPR spectrum selected spatial region located far where model plate applied. By analyzing signal slices equation we have obtained values diffusion coefficient surface relaxation rate.
