amorphous thin films deposited by pulsed laser ablation

Soft magnetic Fe-Cu-Nb-Si-B amorphous thin films with thickness ranging between 100-200 nm have been prepared onto glass and silicon substrates by means of pulsed laser ablation of amorphous Fe73.5Cu1Nb3Si15.5B7 ribbons. The values of the refraction and extinction indices at 632.8 nm were found to be 2 and 2.3, respectively. The surface coercivity increases with the increase of the film thickness. For the same thickness, the coercivity of the films deposited onto silicon substrates is about 35 % smaller
