Neutron-scattering measurements have been performed on (Nd,Pr){sub 2{minus}{ital x}}Ce{sub {ital x}}CuO{sub 4} (0.0{lt}{ital x}{lt}0.125) single crystals. All samples exhibit three-dimensional (3D) long-range magnetic order; the temperature dependence of the 2D magnetic correlation lengths in all is similar in character to that observed in pure and lightly doped La{sub 2}CuO{sub 4} albeit with renormalized spin stiffness constants {rho}{sub {ital s}}. Thus, in the nonsuperconducting doping regime the hole- and electron-doped systems exhibit analogous magnetic behavior except for the drastically different dopant-concentration scales for the destruction of magnetic order.
