Center for Superconducting and Magnetic Materials

The Center for Superconducting and Magnetic Materials (CSMM), founded at OSU in 1995, has its strongest emphasis on superconducting materials, including their formation and structure as well as their magnetic and electrical properties. CSMM has research programs in various aspects of superconducting materials, including MgB2, Nb3Sn, and YBCO. Phase formation, reactions, diffusion, and microstructure are studied in MgB2 and Nb3Sn, as well as transport, magnetic, and flux pinning. Its activities embody a wide range of Materials Science as well as Engineering topics. Those presently under investigation include: high-pressure/high-temperature study of the Mg-B phase diagram, phase evolution and A15 Nb3Sn formation within the ternary Nb-Sn-Cu diagram, microstructure and critical current density optimization in MgB2 and Nb3Sn superconducting wires, formation and properties (microstructural, electrical, and magnetic) of films formed by pulsed laser deposition, electropolishing characteristics of niobium for superconducting RF (SRF) cavities, and bulge testing of niobium tube in support of a program for hydroforming SRF cavity strings.
