High-pressure study of the Raman modes in YBa2(Cu0.96Ni0.04)4O8
(American Physical Society, 1999)We present a study of the Raman phonons in YBa2(Cu0.96Ni0.04)4O8 under hydrostatic pressure in the superconducting phase. A comparison with our earlier work on the undoped YBa2Cu4O8 shows that the pressure coefficients ...
