Pressure effects on the electrical resistivity and thermoelectric power of La-Sr CuO-have been studied. The electrical resistivity decreases and thermoelectric power increases under pressure. The relative changes of these quantities are rather large in small x region and decreases with increasing

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
Ultrasonic and specific-heat measurements have been performed across the superconducting transition on a single crystal of Lax.s6Sr014CuO 4. A pronounced jump of the elastic constant AC33(Tc) = -0.15 GPa is observed at To = 34 K as well as a specific-heat jump Acr/T ~ = 9.6 mJ/K2mol, whereas a jump
