Spin-lattice relaxation time ðT 1 Þ and phase memory time ðT M Þ of shallow donors in 3C-, 4H-and 6H-SiC have been measured in time domain by using pulsed EPR technique. The temperature dependence of T 1 suggests that the Orbach process should be frozen at relatively high temperatures. Shallow donor
