We report on the first observation of the electron paramagnetic resonance of iron impurity in SiC:Fe crystals. Iron exists in the Fe
(3d) charge state with electron spin S = 5/2 and seems to occupy silicon sites in the 6H-SiC lattice. The EPR spectrum of Fe in SiC shows a characteristic anisotropy of an S = 5/2 system in a strong axial crystalline field with fine structure parameter D = 0.25 cm. The g-factor is nearly isotropic, g = 1.99. The possibility of using iron doping to obtain semi-insulating SiC crystals is discussed.
