Behaviour Of Both In-Plane And Out-Of-Plane Resistivities Of Nd2-Xcexcuo4 Single Crystals

The norma state transport properties of as-grown Nd2-xCexCuO4 single crystals with x=0; 0.13; 0.17; 0.18 are investigated in temperature range 1.7 K less than or equal to T less than or equal to 300 K and at the magnetic field up to B = 5 T. It was found that the increase of the Ce-content leads to the change of the conduction law from semiconductor-like behaviour for undoped Nd2CuO4 to metallic-like for overdoped single crystals. Anisotropic negative magnetoresistance together with non-metallic behaviour (rho (T) similar to ln T) at low temperatures of the in-plane resistivity demonstrates 2D (or anisotropic 3D) weak localization effect for the as-grown single crystals.
