An investigation of the effect of a magnetic field (B||c) on the behavior of the resistance of a Nd185Ce0 ^CuO,^ single crystal (Tc= 14 K) showed that the transition into the normal phase can be interpreted on the basis of the theory of dynamic scaling for the conductivity of disordered two-dimensional (2D) systems. The temperature dependence R~ In Γ of the normal-phase resistance at temperatures T^s 10 К corresponds to weak localization in the 2D system. © 1995 American Institute of Physics.
