Enhanced magnetic ordering by impurity Fe substitution on electron-doped superconductors Eu Ce Cu Fe O.

Crystal structure and magnetic properties are two important properties of superconducting materials that need to be studied. We partially substituted the Cu with a magnetic impurity Fe in the electron-doped superconducting cuprate of Eu Ce Cu Fe Oα-δ (ECCFO) to investigate the effect of Fe impurity substitution on crystal structure and magnetic properties. In this study, we have chosen concentrations of = 0.
