© 2020 Elsevier LtdThe magnetic susceptibility in the high-quality epitaxial films Nd1.82Ce0.18CuO4/SrTiO3 with different orientation of the c-axis of electron-doped superconductors Nd1.82Ce0.18CuO4 was investigated. The strong anisotropic behavior of the magnetic susceptibility versus external magnetic field χ||(H) and χꓕ(H) at H<10 kOe and highly anisotropic temperature dependencies of the magnetic susceptibility χ||(T) and χꓕ(T) at low magnetic field H = 100 Oe is associated with different magnetic ordering of Nd3+ (Ce4+) rare earth magnetic ions and copper ions at different orientations of the external magnetic field with respect to the conducting planes of CuO2. The presence of the residual short ranged antiferromagnetic ordering of copper ions even in the overdoped region leads to magnetic anisotropy in the conducting planes.
