Popis: | The Hall effect of epitaxial YBa 2 Cu 3 O 7-x (T c ≃90 K) and Bi 2 Sr 2 CaCu 2 O y (T c ≃80 K) films has been investigated. In both compounds the Hall coefficients R H (B∥c axis) in the normal phase is positive and exhibits a strong temperature dependence, which is more pronounced in YBa 2 Cu 3 O 7-x than in Bi 2 Sr 2 CaCu 2 O y . On the basis of a renormalized two-dimensional tight-binding band structure the normal-state Hall coefficient R H has been calculated as a function of doping concentration and temperature using the relaxation-time approximation |
