Abstract
The isotope coefficient α has been studied in the context when the Fermi level is close to the van Hove singularity. In this approach, we consider the interaction is related to the magnetic excitations at high temperature. An analytical expression for the isotope effect is obtained in the weak coupling limit. Our results show that when the superconducting transition temperature increases the isotope coefficient decreases in qualitative agreement with experimental results.
