ShareTHE HEAT CAPACITY OF YBA(2)CU(3)O(7) AND YBA(2)CU(3)O(6) IN THE RANGE 0.4 AND 20 K: EVIDENCE FOR AN INTRINSIC T-TERM.
Author(s) : COLLOCOTT S. J.
Type of article: Article
Summary
THE HEAT CAPACITY OF A NUMBER OF THESE SAMPLES HAS BEEN MEASUR ED IN THE RANGE 0.4 TO 20 K TO INVESTIGATE THE EFFECT OF PARAMAGNETIC CHEMICAL AND PHASE IMPURITIES. THE ROLE OF VARIOUS IMPURITY PHASES, INCLUDING BACUO(2) IS DISCUSSED. AN INTRINSIC TEMPERATURE DEPENDENCE TERM IS DISCUSSED IN TERMS OF THE RESONATING-VALENCE-BOND MODEL AND TUNNELLING DUE TO TWO-LEVEL SYSTEMS.
