N2 - In this work studied has been the fabrication method of columnar-structured Fe thin film for manifestation of a shape anisotropy in Fe-Cr alloy system, in which the phase separation occurs naturally by the thermal treatment. In order to obtain such a columnar structure, we have utilized the phase separation on a Sn-nanoparticle-dispersed Si substrate, by exploiting an excellent metallurgical affinity of Fe and Sn, and moreover we have employed applying an external magnetic field. Resultingly, we have found that the columnar-structured Fe thin films are likely to be formed after annealing. Thus obtained Fe-Cr-Sn thin film was found to exhibit a high shape-magnetic anisotropy, where the out-of-plane coercivity Hcl was about 750 Oe, being five times larger than the in-plane coercivity Hck of about 150 Oe.
