The origin of the observed perpendicular magnetic anisotropy (PMA) in Ni/Cu(001) for thick Ni layers is investigated using the {ital ab initio} full potential linearized augmented plane wave method. With the aid of the state tracking and torque approaches, very stable results are obtained for the magnetocrystalline anisotropy (MCA) energies for both the Ni/Cu(001) overlayer systems and the distorted bulk fct Ni. We find that the PMA is due mainly to the strain induced bulk contribution rather than to interfacial hybridization. The calculated value of the bulk MCA energy, 65 {mu}eV/atom, is very close to recent experimental data extrapolated to zero temperature, 70 {mu}eV/atom. {copyright} {ital 1997 American Institute of Physics.}
