Abstract

Conventional superconductivity is described by its interactions of electrons through a vibrational mode called phonons. For high temperature superconductors (HTS), the mechanism which explains its superconductivity is still unknown. Various measurement techniques have been established to study the mechanism behind HTS including looking at the effect of altering the mass of oxygen in the copper-oxide planes of cuprate crystal lattices from 16 g/mol to 18 g/mol, also known as the isotope effect. While the results of previous experiments are still inconclusive, I aim to investigate this effect using magnetometry, Raman spectroscopy, and laser angle resolved photoemission spectroscopy (ARPES) in order to find evidence for a particular pairing mechanism.
