Abstract
The 2D weak localization effects at low temperatures T = (0.2-4.2)K have been investigated in nonsuperconducting sample Nd1.88Ce0.12CuO4-d and in the normal state of the superconducting sample Nd1.82Ce0.18CuO4-d for B>Bc2. The phase coherence time and the effective thickness d of a conducting CuO2 layer have been estimated by the fitting of 2D weak localization theory expressions to the magnetoresistivity data for the normal to plane and the in-plane magnetic fields.
