Abstract

We report on the preparation, by means of the pulsed laser ablation technique, of particulate Fe films. Our results for the morphologic and magnetic characterization of these films showed that they were formed by quasi-spherical particles having average sizes in the range from 13 up to 25 nm and that they had room temperature coercive force values in the range from 240 Oe down to typical bulk-like Fe values. Measurements of the field evolution of the isothermal and demagnetization remanences evidenced that the hysteretic behavior of the films was strongly influenced by the occurrence of interparticle interactions
