Summary:The magnetocrystalline anisotropy energy and anisotropy of the orbital angular momentum have been calculated ab initio for YCo 5 using the LMTO method. Quantitative agreement with experiment is found if a recently proposed orbital polarization correction is included. The anisotropy of the orbital angular momentum and the energy are strongly correlated. The crystal field parameters at the RE site in RECo 5 compounds, calculated using the FLAPW method, have the correct sign and are comparable to the experimentally observed values.
