Popis:	The electrical transport properties of the cuprate superconductor Nd{sub 1.85}Ce{sub 0.15}CuO{sub 4{minus}{delta}} have been studied in the mixed state and in the normal conducting state by measuring the Hall voltage and the longitudinal voltage of an epitaxial thin film. A broadening of the resistive transition with increasing fixed magnetic field and a sign reversal of the Hall effect in the mixed state were observed. In the normal state, the zero-field resistivity shows a quadratic temperature dependence. Magnetoresistance measurements for {ital T}=102 and 55 K yield a {ital B}{sup 2} dependence up to {ital B}=10 T without any saturation tendency. The normal-state Hall coefficient is temperature dependent with a sign change from negative to positive for decreasing temperature. The data can be interpreted within a two-band model.
