Facile Synthesis and Magnetic Characterizations of Single-Crystalline Hexagonal Cobalt Nanoplates

Single crystalline hexagonal cobalt nanoplates with diameter ca. 260 nm and thicknesses of 10 nm were synthesized through a one step simple reduction process using a soft-template approach. The sample exhibits a ferromagnetic behavior with a high coercivity field. The effect of the shape anisotropy on magnetic properties was investigated using numerical simulations, showing good agreement with experimental results. © 2012 Elsevier B.V.
