Abstract

We produced FeCo and FeCr binary nanocluster wire (NCW) arrays by thermally decomposing mixtures of Fe(CO)₅/Co₂(CO)₈ and Fe(CO)₅/Cr(CO)₆ metal carbonyl vapors, respectively. For both FeCo and FeCr binary NCW arrays, the diameters of individual NCWs ranged from 10 to 30 nm and the NCWs existed as bundles. For both FeCo and FeCr binary NCW arrays, we observed lower saturation magnetic fields and higher M _r/M_s for the magnetic field applied parallel to the NCWs than those for the magnetic field applied perpendicular to the NCWs, respectively. We also observed higher coercivities in FeCo binary NCW arrays than those in FeCr binary NCW arrays, due to the antiferromagnetic property of Cr.
