| Popis: | Samples of coal from the Donetsk basin (carbon content ~90 mass%) in both lump and powder forms were studied by continuous-wave electron spin resonance (ESR) at room temperature in air. Inversion of the ESR signal (being in phase with modulation of the constant magnetic field) with an increase of lump size along the magnetic component of the microwave field was observed in the cavity of the radiospectrometer. |
