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