UPPER AND LOWER CRITICAL FIELDS OF TAS2(PYRIDINE)1/2

The temperature dependences of the upper critical fields, Hc2//,⊥, and the lower critical field, Hc1//, have been measured on the single crystal of the layer structure TaS2 intercalated with pyridine. Some basic parameters concerned with the superconducting properties have been determined using the anisotropic Ginzburg-Landau theory. The value of the specific heat jump at Tccalculated from the experimental data shows a fairly good agreement to the previous results of the specific heat measurements. This fact seems to indicate the applicability of the anisotropic G-L theory to TaS2(Py)1/2. © 1979, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
