NpP is the first member of the Np-monopnictide series which crystallises in the simple cubic NaCl-type structure. Previous work has shown that these compounds exhibit peculiar electronic and magnetic properties owing to the hybridisation of f-electrons with band electrons. The main characteristic of these compounds is the existence of very anisotropic interactions, the origin of which is the p-f mixing which becomes larger on going from light to heavy pnictides. In this paper the transport properties of the Np-monopnictides are described, with special emphasis on NpP now available in single crystalline form. Resistivity, Hall resistivity and magnetoresistance were measured on a single crystal of NpP. The measurements were performed between 1.5 and 300 K using a dc-four probe method. Special care was taken to eliminate spurious effects such as thermoelectric voltage and Hall probe misalignment. Results of the measurements and conclusions that can be drawn from them are presented.
