Abstract
Measurements of magnetoresistivity, Seebeck, Nernst and Hall coefficients in the mixed state for “Bi:2212” epitaxial thin films, prepared by DC sputtering, and doped with Gd (0≤x≤0.5) and Zn (0≤y≤0.03) in magnetic fields between 0 and 5 T, and the temperature range 5–50 K are reported. The critical temperatures, the Hall, Nernst and Seebeck coefficients depend strongly on Zn and Gd contents in the samples. The tails of the transport coefficients versus temperature curves are caused by fluctuation effects, which increase with increasing magnetic field. These anomalous behaviors validate the theories based on time dependent Ginsburg–Landau theory.
