摘要：

Resistive and magnetic measurements of the superconducting transition in good quality single crystals of YBa2Cu3O7-δ and La2-xSrxCuO4 an in good polycrystalline samples of Ba1-xKxBiO3 are used to derive the temperature dependence and anisotropy of the upper critical field. Comparison of the results shows several common features, most notably the existence of upward curvature in the temperature dependence of the upper critical field. The definition of Tc from resistance curves and the origin of the upward curvature in the upper critical field are discussed.
