High-Temperature Superconductor Materials Database Available For PC Users

A new NIST database for personal computers provides materials researchers in industry, federal laboratories and universities with rapid access to carefully evaluated information on 24 thermal, mechanical and superconducting properties for oxide superconductors. The NIST High-Temperature Superconductors Database, Standard Reference Database 62, is now available from the Commerce Department's National Institute of Standards and Technology.

The range of materials in the PC database covers approximately 130 series of compounds derived from the yttrium-barium-copper-oxygen (Y-Ba-Cu-O), bismuth-strontium-calcium-copper-oxygen (Bi-Sr-Ca-Cu-O), thallium-strontium-calcium-copper-oxygen (Ti-Sr-Ca-Cu-O), and lanthanum-copper-oxygen (La-Cu-O) chemical families, along with numerous other variants of the cuprate or copper-containing and bismate materials that are known to have superconducting phases.

The materials in SRD 62 are described by specification and characterization information that includes processing details and chemical compositions. Physical characteristics such as density and crystal structure are given in numeric tables. All measured values are evaluated and supported by descriptions of the measurement methods, procedures and conditions.

The current data have been collected from approximately 400 papers published in the years 1987-1993 and evaluated in terms of materials characterization and how experimental conditions have been controlled. In all cases the sources of the data are fully documented in a comprehensive bibliography.

NIST High-Temperature Superconductors Database, NIST Standard Reference Database 62, PC Version 1.0, is available for $265. A special discount is available for multiple copies. The database requires MS-DOS 5.0 or higher; 80386, 80486 or Pentium; 7.5MB disk space; 4MB RAM, and Windows (TM) 3.1 or higher.

To order PC Version 1.0, contact the Standard Reference Data Program, Rm. 113, Bldg. 820, NIST, Gaithersburg, Md. 20899-0001, (301) 975-2208, fax: (301) 926-0416, e-mail: srdata [at] enh.nist.gov.

As a non-regulatory agency of the Commerce Department's Technology Administration, NIST promotes U.S. economic growth by working with industry to develop and apply technology, measurements and standards.
