Abstract
Electronic properties such as temperature dependence of resistance (R) and Hall coefficients (RH) were measured for synthesized Bi-Sr-Ca-Cu-O thin films with a zero resistance temperature (TC) of 107 K, 70 K, and bulk ceramics with a TC of 107 K. The extrapolation of the normal resistance to zero degrees was always negative for a high TC phase, but usually positive for a low TC phase. It was clearly recognized that temperature dependence of the Hall coefficient of a high TC phase film and bulk ceramics is stronger than that of a low TC phase film. In addition, the temperature dependence of the inverse Hall coefficient (1/RH) of high TC phase films and bulk ceramics was proportional to temperature.
