Low-temperature scanning tunneling spectroscopy on the highly overdoped La 1.78 Sr 0.22 CuO 4 (T c = 27 K) single crystal reveals gap inhomogeneity at 4.2 K. The energy gap D observed in the tunneling spectra distributes around 7 meV: it ranges from 4 to 20 meV. The spectra with smaller D (4-10 meV)

Raman scattering measurements in zero and non-zero magnetic fields up to 14 T have been performed on a La 2Àx Sr x CuO 4 single crystal with x $ 1=8. A substantial field-induced enhancement of the electronic Raman intensity is observed, especially in the high frequency region around 2000 cm À1 .
Neutron scattering experiments for La 1:85 Sr 0:15 Cu 0:98 Ni 0:02 O 4 (T c ¼ 28 K) demonstrated that well-defined incommensurate peaks appear in the superconducting state, giving an enhancement of v 00 ðq IC ; xÞ at $1 meV associated with a sharpening of peak width. Thus, the Ni impurities induce l
The DC magnetic susceptibility of single-crystal La2\_~r~CuO, (x= 0.08, 0.12, 0.14, 0.15, 0.19 and 0.26) was measured from 30 to 300 K under the magnetic field H= I T. All the samples have shown anisotropic susceptibilities, where the susceptibility with HL CuO2 plane is 1.5-3 times as large as that
