Resumen:
We present magnetic resonance results obtained at L, X, and Q bands (1.2, 9.4 and 34 GHz, respectively) on ferromagnetic nanowires with a hysteresis cycle characterized by a remanent magnetization Mr=Ms~0.92 and a coercive field Hc= 1.0 kOe. The hysteretic response of the ferromagnetic resonance spectra is discussed in terms of independent contributions of the nanowires aligned along and opposite to the applied field. We will discuss the implications of this study on the magnetic resonance in nanoparticles and other systems with large anisotropy.Mr=Ms~0.92 and a coercive field Hc= 1.0 kOe.
