Abstract
The temperature dependence of the volume change associated with the hi gh temperature superconductivity in La1.85Sr0.15CuO4 is estimated by u sing the Landau-Ginzburg theory and by assuming a uniform expansion of Cu 3d-electron band width with lattice contraction. Though the calcul ated absolute value is smaller but the order of magnitude and the tend ency of the temperature variation are in agreement with the experiment s.
