Magnetic susceptibility measurement of single iron/cobalt carbonyl microcrystal by atmospheric magnetophoresis
Original language description
In this study, the use of an innovative atmospheric magnetophoresis, which enables us to measure the mass magnetic susceptibility and mass of a microparticle simultaneously, was demonstrated. Using this technique, we determined the magnetic susceptibility of a crystalline deposit of iron/cobalt carbonyl, mainly composed of Fe-2(CO)(9), which was prepared photochemically from a gaseous mixture of iron pentacarbonyl (Fe(CO)(5)) and cobalt tricarbonyl nitrosyl (Co(CO)(3)NO). The mass magnetic susceptibility and the characteristic relaxation time of the microcrystal were (7.0 +/- 1.9) x 10(-9) m(3) kg(-1) and (5.6 +/- 2.2) x 10(-4) s, respectively. The observed magnetic susceptibility shows that the microparticle was paramagnetic. Assuming that the densitywas equal to that of Fe-2(CO)(9) (2.1 x 10(3) kg m(-3)) and that the shape of the particle was spherical, a hydrodynamic radius of 4.7 mu m and a mass of 0.91 ng were observed. It was suggested that Co was incorporated in Fe-2(CO)(9).
