Abstract : During the 1995-96 year of the research program on 'Microwave and Transport Studies of Superconducting Films of YBCO and Fullerenes,' the effort was focused on several projects. The main highlight was a collaborative study of the nonlinear microwave properties of superconducting YBa2Cu3O(7-x) (YBCO) which was carried out with researchers at Rome Labs and the MIT Lincoln Laboratory. During this year Nathan Belk completed his Ph.D. thesis entitled 'Electronic Transport and Magnetic Properties of Disordered High-Tc Materials.' Joe Habib made Significant progress with his study of microwave losses in individual Josephson junctions. A new graduate student, Chris Lehner, who is an Army Captain, joined the group on assignment from the US Army, and is working on the modeling of microwave losses in superconducting circuits. Continued progress was made with the use of femtosecond optics to study superconductivity and the associated phenomena in alkali metal doped C60 materials.
