IDENTIFICATION OF SUPERCONDUCTIVITY IN LABACUO BY LUMINESCENCE SPECTRA: COMPARISON BETWEEN OPTICAL AND MAGNETIC MEASUREMENTS.

[In Russian. / En russe.]

Author(s) : PANFILOV A. S.

Type of article: Article

Summary

COMPARATIVE MEASUREMENTS OF EMISSION SPECTRA, MAGNETIC SUSCEPTIBILITY AND RESISTIVE CHARACTERISTICS OF LABACUO SAMPLES ARE PERFORMED IN THE TEMPERATURE RANGE OF 6-140 K. THE IMPURITY NARROW-BAND EMISSION LINE AT 3. 36 ELECTRONVOLTS IS SHOWN TO BE SENSITIVE TO THE PHASE-TRANSITION POINTS, INCLUDING THE SUPERCONDUCTING PHASE ONSET. THE IMPURITY EMISSION SPECTRA CAN BE LOCAL OPTICAL PROBES TO CONTROL ELECTRON AND LATTICE CHANGES IN HIGH TEMPERATURE SUPERCONDUCTORS.
