| Abstract: | A series of Fe xCu 1 x granular films were fabricated by rf magnetron sputtering and the R I (resistant current) relation was studied systematically. This relation changed with the thickness of the film, the atom ratio x of iron to copper and the annealing conditions. The experiment shows that even a small measuring current also affects the structure and properties of the nano size granular film seriously. As a result of big current measurment, the film exhibits an anomalous resistance temperature characteristic and the structure of the film crystallizes partly. A preliminary explanation is given to the experimental phenomena. |
