Experimental studies are made on the effect of ion, electron and γ-irradiations on thermal stability and microstructure of amorphous electrodeposited CoP alloy films. It is found that irradiation results in a deterioration of the thermal stability of the amorphous state and under definite dose of boron or hydrogen ions the effect of ion-stimulated atoms regulation is observed. It is shown that ions irradiation destroy the granular microstructure. It leads to the destruction of the perpendicular magnetic anisotropy in these films and greatly improves their magnetic characteristics.
