Abstract

<p>The shape anisotropy dominates the material properties of the 300 nm thick evaporated particles, resulting in higher coercivity and lower remnant magnetization. The results of VSM measurements of rod-shaped particles show the highest coercivity among all particles, measuring as high as 37 Oe and remnant magnetization decrease from 0.7 to 0.3 with increase of layer thickness.</p
