NEGATIVE MUON SPIN ROTATION STUDIES ON SINGLE-CRYSTAL LA2CUO4+DELTA ABOVE TN

The negative muon spin rotation (mu-SR) experiments have been performed on the La2CuO4+delta single crystals (T(N) = 255K) in the paramagnetic region. The temperature dependence of the two components of paramagnetic shift was obtained from the electron spectrum emitted from mu-O. The hyperfine coupling constants, A(hf)1 and A(hf)2 (A(hf)1 > A(hf)2) obtained from the K - chi-plot are proposed to be ascribed to the O(1) and O(2) sites, respectively.
