CU-63 NMR-STUDY OF INFINITE-LAYER COMPOUND SR1-XLAXCUO2

We present the Cu-63 NMR studies on powder samples of an electron-dope d infinite-layer high-T-c cuprate superconductors Sr1-xLaxCuO2 (x = 0, 0.07, 0.16). We have found the decrease of magnetic shift due to the superconducting transition. The temperature dependence of the spin-lat tice relaxation rate (T1T)(-1) demonstrates non-Korringa Curie-Weiss W ee behavior in normal state. These results are very similar to the gen eral case of hole-doped high-T-c superconductors. The decrease of the quadrupolar frequency with increasing the doping level has been found.
