A. Buzdin et D. Feinberg, ANISOTROPIC SUPERCONDUCTING FLUCTUATIONS IN A MAGNETIC-FIELD - SPECIFIC-HEAT, MAGNETIZATION AND ANGULAR-DEPENDENCE, Physica. C, Superconductivity, 220(1-2), 1994, pp. 74-80
The Gaussian theory of superconducting fluctuations in an uniform magn
etic field is presented above the H-c2 line, for an anisotropic superc
onductor. The situation of an arbitrary orientation of the field is in
vestigated by means of a scaling transformation. The specific heat and
the diamagnetic susceptibility are calculated. In particular the fluc
tuation torque is compared to the mean-field one just below H-c2 and i
n the London regime. A comparison is made with existing experiments on
specific heat and torque in high-T-c compounds.
