The constant Ku of magnetic uniaxial anisotropy is measured in sputtered amorphous Gd–Co films by different methods. Considerable discrepancies are found between the results of static and of ferromagnetic resonance measurements, especially in the region of magnetic compensation. The reasons for the different results are probably inhomogeneous composition and microstructure of the films and slightly field‐dependent magnetic parameters of amorphous Gd–Co. To get more insight in the origin of Ku in amorphous Gd–Co, measurements in a broad temperature range are performed before and after annealing. The results show clearly two main contributions to Ku. Atomic short range order leads to positive Ku and disappears during annealing. Stresses in the films produce negative Ku at temperatures below the temperature during preparation and are not significantly influenced by annealing.
