Abstract
The itinerant-state magnetocrystalline anisotropy energies (MAE) of RCo5 (R = Y, La. Pr, Nd. Sm. Gd) have been determined by relativistic density-func tional calculations in local spin density approximation, with additionally taking into account orbital polarization. The calculated MAEs are found to be strongly affected by changes of the lattice geometry (c/a ratio and volu me) resulting from (a) uniaxial strain in YCo5 and (b) the lanthanide contr action along the RCo5 series.
