The electrical transport properties of the cuprate superconductor Nd&»Ceo»Cu04 z 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 T =102 and 55 K yield a B dependence up to B =10 T without any saturation tendency. The normalstate Hall coeScient is temperature dependent with a sign change from negative to positive for decreasing temperature. The data can be interpreted within a two-band model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
