Evl. Demello et C. Acha, STUDY OF THE PHASE-DIAGRAM AND THE T-C PRESSURE-DEPENDENCE FOR HGBA2CUO4-DELTA SUPERCONDUCTORS, Physica. C, Superconductivity, 282, 1997, pp. 1819-1820
We apply a method recently derived based on the extended Hubbard Hamil
tonian to obtain the superconducting critical temperature dependence w
ith carrier density of HgBa2CuO4-delta. We show that this approach can
be used to study the effects of pressure and reproduces for the first
time the experimental data for the whole doping regime and their high
and low pressure dependence.
