Abstract
Measurements of the spin-lattice relaxation rate and Knight shift on p rotons in hydrogen-doped superconducting H0.2La1.8Sr0.2CuO4 samples ar e performed in the temperature range 4.2-300 K. An anomalous behavior of the spin-lattice relaxation rate is observed at low temperatures T similar to 20 K. A model is constructed that explains the appearance o f carrier-depleted regions in the bulk of the semiconductor on the bas is of the formation of a charged defect (proton).
