  • Abstract
    Superparamagnetic CoIr nanoparticles were proposed as new isotropic magnetic materials that satisfy both high blocking resonance frequency, fb , and ferromagnetic resonance frequency, fr. The magnetic material used has negative magnetocrystalline anisotropy. Magnetisation process of the particles were obtained. The phase transition from superparamagnetism to ferromagnetism was also investigated.
