Abstract
Control of Co particle size was archived by a germ-growth method during inv erse micelle synthesis. Magnetic coercivity and blocking were both a functi on of the particle size, which ranged from 38 to 88 Angstrom. Interparticle dipolar interaction was proven to be important in order to interpret the m agnetic properties for large-size particles.
