O. Navarro, THERMODYNAMIC PROPERTIES OF THE SUPERCONDUCTORS BAPB0.7BI0.3O3 AND BA0.7K0.3BIO3 USING ELIASHBERG THEORY, Journal of low temperature physics, 105(3-4), 1996, pp. 855-860
We present results of a thermodynamic analysis for the superconductors
compounds BaPb0.7Bi0.3O3 and Ba0.7K0.3BiO3 are calculated making use
of the Eliashberg theory spectra alpha(2)(omega)F(omega) as calculated
by Shirai et al. BaPb0.7Bi0.3O3, several models of the alpha(2)(omega
)F(omega) were studied looking for a better agreement with experimenta
l data. The a simple constant scaling (C = 1.25) of the Shirai's spect
ra, The functional derivative of the deviation function D(t) with resp
ect to changes in alpha(2)(omega)F(omega) is also calculated.
