Type of article: Article

Summary

A COMMON MINERALOGICAL TECHNIQUE FOR IDENTIFYING INDIVIDUAL CRYSTALS IN A HETEROGENEOUS, POLYCRYSTALLINE SAMPLE INVOLVES THE OBSERVATION AT ROOM TEMPERATURE OF THEIR COLOURS IN REFLECTED POLARIZED LIGHT (COLOURS OF POLARIZATION). HERE THE AUTHORS PRESENT THE OBSERVATION THAT A BROWNISH YELLOW (GOLDEN) COLOUR OF POLARIZATION IS NOT ONLY CHARACTERISTIC OF THE YBCO SUPERCONDUCTOR, BUT OF THE CUPRATE SUPERCONDUCTORS IN GENERAL AND IS CORRELATED WITH THE OCCURRENCE OF SUPERCONDUCTIVITY.
