A Study of Isotope Effect and Evaluation of Critical Exponent of High Tc Superconductor

A. K. Mishra and L. K. Mishra

Abstract

Using the theoretical model of S. Yoksan, we have studied the isotope effect in high Tc superconductors. This model takes into account the nearest neighbor interlayer hopping. Our theoretical results indicate that the value of isotope exponent α of high Tc superconductor is very small
