Magnetic-field-induced Synthesis of Co Filtering Film Consisting of Co Nanowires

摘要

Co filtering film consisting of numerous compact Co nanowires with a diameter of ca. 10 nm was prepared by a magnetic-field-induced synthetic route. Room-temperature coercivity (Hc) of the Co filtering film measured with the applied magnetic field parallel and perpendicular to the film plane was 210 and 481 Oe, respectively, which was significantly higher than that of bulk Co film.
