Abstract

Uncoated and oleic acid coated Fe

nanoparticles are synthesized by a co-precipitation method. These nanoparticle samples are characterized by x-ray diffractometer, transmission electron microscope and vibrating sample magnetometer. Both samples contain 7 nm sized similar magnetic particles. Temperature variation of the zero field cooled susceptibility of the uncoated particles peaks at 120 K. The zero field cooled and the field cooled susceptibility curves bifurcate at 195 K. The peak temperature and the bifurcation temperature decrease due to presence of oleic acid layers around particles. Thermoremanent magnetization of both samples decrease with time but the decay rate is lower for the oleic acid coated particles. Such magnetic nanoparticle systems have potential applications in biomedicines.

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
