The structure and magnetic properties of sputtered La-Co alloy films have been studied. Less than 10 A/m (100 m Oe) coercivity can be obtained in amorphous La 100-xCo x films around x = 80 and the coercivitx of amorphous La 20 Co 80 film depends on the thickness of the film. The magnetization behaviour has been examined for the films with different compositions through magnetic hysteresis loops. An excellent rectangular magnetic hysteresis loop was obtained for films with thickness less than 60 nm.
