Journal of Physical Studies 5(1), 46–48 (2001) DOI: https://doi.org/10.30970/jps.05.46 THE INFLUENCE OF NEAR FERMI LEVELS STRUCTURE OF STATES DENSITY ON NORMAL PROPERTIES OF THE YBa2Cu3O7 SUPERCONDUCTOR O. J. Babych, R. V. Lutciv Ivan Franko National University of Lviv, Chair of Radioelectronic Materials Science, 50 Dragomanov Str., Lviv, UA-79005, Ukraine

The calculation of temperature dependence of thermopower, magnetic susceptibility, electron heat capacity and electroconductivity of a high-temperature YBa$_2$Cu$_3$O$_7$ superconductor has been conducted using states density $g(E)$ in compliance with the band theory and somewhat modifed near $E_F$. We have received a good agreement between the calculated and experimental data at the temperatures $T>T_C$.
