Abstract
Elongated ferromagnetic amorphous nanoparticles, with an average diame ter of 25 Angstrom have been created by heavy ion irradiation of param agnetic crystalline YCo2 thin films. As expected in such elongated par ticles, a perpendicular shape anisotropy is observed. The anisotropy f ield decreases as the fluences increases, as a result of the onset of dipolar interactions between the nanoparticles.
