| Abstract | The effect of samarium content on magnetic interaction intensity of cobalt samarium alloys in the form of thin films deposited on silicon (100) substrates has been studied. These films were fabricated using dc magnetron sputtering technique. It was found that the intensity of magnetic interaction between grains in the films was reduced as samarium content increased. It was also showed that the coercivity of the films increases and reaches a maximum value at around 19 22 atomic % samarium, followed by a decrease with further increase in samarium concentration. The hysteresis loop squareness of the samples decreases as samarium content increases. Moreover, the degree of crystalline of the films decreases as samarium concentration is increased. Thus the increase of coercivity of the films in this range is also discussed. |
