AbstractThe magnetic properties of thermally annealed Fe nanocrystals prepared through ion implantation in single crystal yttrium-stabilized zirconia (Y0.2Zr0.8O19) were studied by quasistatic hysteresis loop measurements and by pulsed ferromagnetic resonance. The change of coercivity and the shape of hysteresis loops at different annealing temperature can be interpreted through the size increase of the nanocrystals. Magnetostatic coupling must be taken into account to understand the rise times of the ferromagnetic resonance, especially for the samples annealed at higher temperature.
