[In Russian. / En russe.]

Author(s) : GUREVIC A. M.

Type of article: Article

Summary

THE MEASUREMENT RESULTS ON LOW-TEMPERATURE (1.5-20 K) HEAT CAPACITY ARE GIVEN FOR A NUMBER OF HTS SAMPLES WITH SUCCESSIVE SUBSTITUTION OF THE METAL ATOMS IN VARIOUS POSITIONS. THE EXPERIMENTALLY OBSERVED ANOMALIES MAY BE RELATED TO THE RECONSTRUCTION OF THE ELECTRON AND MAGNETIC SUBSYSTEMS. THE DEBYE TEMPERATURES ARE CALCULATED AND THE BOUNDARY FREQUENCIES OF THE ACOUSTIC SPECTRUM ARE EVALUATED FOR ALL THE CERAMICS STUDIED.
