摘要：
The misfit layer compound (LaSe)(1.14)(NbSe2)(2) undergoes a superconducting transition at 5.43 K. The anisotropy of this compound calculated by the angular dependence of the critical field at 4.2 K is 35 and its perpendicular resistive critical magnetic field, H-perpendicular to*, taken at a fraction of the normal state resistance, rises steeply when the temperature is reduced with an upward curvature and does not show any sign of saturation down to 0.050 K. This anomalous behaviour is probably induced by important thermal fluctuations. (C) 1997 Elsevier Science S.A.
