THE EFFECT OF LOWER OXYGEN ON MAGNETIC PROPERTIES OF WEAK LINKS IN YBACUO(7-X) POLYCRYSTALS.

[In Russian. / En russe.]

Type of article: Article

Summary

FIELD DEPENDENCE OF MAGNETIZATION IN LOW MAGNETIC FIELDS IS OBTAINED FOR YBACUO POLYCRYSTAL SAMPLES WITH DIFFERENT OXYGEN CONTENTS (X BETWEEN 0.10 AND 0.53). ANALYSIS OF THESE CURVES SUGGESTS A JOSEPHSON MECHANISM OF CONDUCTIVITY BETWEEN THE CERAMICS GRANULES. NONMONOTONIC VARIATION IN THE MAGNETIC SUSCEPTIBILITY OF THE SUPERCONDUCTING GRAINS IS OBSERVED WITH AN INCREASE IN THE PARAMETER X. THIS VARIATION CORRELATES WITH THAT IN THE CRITICAL TEMPERATURE OF THE SUPERCONDUCTING TRANSITION ONSET.
