Size-control and Size-selection at the Nanosize Level: Production of CoFe2O4 nanoparticles of unusual high coercivity at room temperature

Chinnasamy C.N., Jeyadevan B., Perales-Perez O., Shinoda K., Tohji K., Kasuya A., University of Puerto Rico, PR

Here, we introduce a solution chemistry technique which involves a `seeding step` under conditions where nucleation and growth rates of particles are controlled to produce single domain well-crystallized CoFe2O4 nanoparticles followed by a size-selective separation [...]

The Microstructure and Computed Magnetic Properties of Nanoscaled Permanent Magnets

Zhang J.X., Zhang T.J., Zhang J.X., Zhang T.J., Cui K., Key State Laboratory of Die Technology, HUST, CN

Magnetic properties of a model nanocomposite magnet were calculated by means of computer simulation, and the effects of the amount of the soft magnetic phase on them were studied. The numerical results show that the [...]
