Abstract

We present ferromagnetic resonance (FMR) and magnetic properties of single domain Y3Fe5O12 (YIG) nanoparticles with an average size of 60 nm. The saturation magnetization shows a diminution of practically 1/3 of the bulk magnetization due to the surface/volume contribution. The coercive force vs. temperature indicates that the particles are single magnetic domains in the blocked state. The FMR data, confirm this state below 350 K. Data of DC-magnetization, magnetic resonance field and linewidth of the FMR spectra are presented. Shape, surface and dipolar contributions to effective anisotropy are discussed. © 2004 Elsevier B.V.
