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

Abstract

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.

Template-free synthesis and characterization of dendritic cobalt microstructures by hydrazine reduction route

“…However, the fcc phase with low coercivity can be used as soft magnetic materials [6]. Until now, Co nanoparticles and one-dimensional (1D) shapes such as nanorods, nanowires, nanobelts, nanofibers, and nanotubes have been successfully prepared by various methods including thermal decomposition organometallic precursors, hydro-/solvothermal and templateassisted synthesis [7][8][9][10][11][12][13][14][15][16].…”
