Abstract
Experimental study of thermal coefficients of both electrical resistance and volume expansion in nanostructured superconducting ceramics YBa2Cu3O7-8 and intermetallic Ti67Al33 alloy was performed. In both compounds we found a correlation between the temperature dependences of these coefficients. Formation and relaxation of charge excitations in conductors with a nonmetallic type of interatomic bonds are discussed. We point that, to explain temperature dependence of the conductivity, one should take into account an anharmonicity of atomic vibrations.
