Superconducting-materials research encompasses the characterization of superconductors in both thin-film and bulk form. Research is centered on a combination of low-temperature production (0.3 K) and generation of high-magnetic fields (9 T).

Superconducting properties are measured by a variety of techniques that include resistance, susceptibility, low-frequency ac loss, and determinations of critical currents in magnetic fields. A high power measurement facility that includes a high dc current supply (up to 800 Amps); a high 60 hz current supply (up to 200 Amps); and a horizontal, rotating superconducting magnet that can generate magnetic fields up to 5T enable measurements of the angular dependence of critical current density and ac losses on magnetic field.

Metallurgical characterizations of specimens under investigation are readily available. The program emphasizes a basic understanding of material properties.
