Superconductivity in Intercalated Graphite
Research report (imported) 2008 - Max Planck Institute for Solid State Research
Elementary properties of the recently discovered alkali-earth intercalated graphite compounds AC6 (A = Ca, Sr, Yb) will be described. These new superconductors with critical temperatures of up to 11.6 K can be described as electron-phonon coupled superconductors with a weakly anisotropic order parameter. Experimental results and ab-initio calculations are in good agreement.
