Ferromagnetic resonance of a magnetic particle using the Landau–Lifshitz–Bloch equation
Source abstract
Abstract
In this work, we employ the Landau–Lifshitz–Bloch equation to study the ferromagnetic resonance of a magnetic nanoparticle assumed in a mono-domain with uniaxial anisotropy. We consider a constant magnetic field applied perpendicularly to the easy axis of anisotropy. We investigated the temperature effect on the resonance spectrum through the complex magnetic susceptibility tensor. We found a decrease in the resonance frequency as the temperature is incremented and a decrement in the resonance field range when the driven frequency increases.
