Toward organic synthesis of a nanometer‐size magnetic particle

Magnetic phenomena in small magnetic particles include giant magnetoresistance and mesoscopic tunneling of quantum magnetization. Further progress in this area requires the availability of particles of uniform size and shape. Recent developments in the synthesis of monodisperse organic particles are discussed, in particular in the area of dendritic molecules, which could lead to an extension of the applications of such particles, which presently range from magnetic memories to permanent magnets.
