SURVEY OF SUPERCONDUCTIVE MATERIALS AND CRITICAL EVALUATION OF SELECTED PROPERTIES.

This publication includes all available data on superconductive materials through March 1975. Data on the bulk elements are critically evaluated, and values on alloys, compounds, and other forms are selected and condensed to indicate the probable value and spread of values observed. Proven nonsuperconductors are noted. Conflict in data values are noted. All data are keyed to the literature in one or more of the tables. Special subdivisions are presented for superconductive materials with organic constituents and for those based on semiconductive materials. The properties presented are superconductive critical temperature, critical magnetic fields, material state and composition including crystal-structure type where noted, a key to thin-film forms, and the presence of thermodynamic data.
