Abstract:
The ferromagnetic resonance spectra depend on the particles sizes and magnetic anisotropies. In the nanometric range these particles are magnetic monodomain, and behave as large magnetic dipoles (superparamagnetic regime). Their resonance spectra in X band can be explained as a convolution of individual particle spectra whose resonance are determined by orientation of external magnetic field, magnetocrystalline anisotropy and magnetostatic field.
