对放置在旋转磁场中的单轴铁磁纳米颗粒进行了大规模的热增强磁化研究。我们阐明了这一现象的性质,并评估了感应磁化对谐振频率的依赖关系。此外,我们揭示了磁偶极相互作用的作用,指出了潜在的应用,并说明了实验观察这种效应的可行性。
The investigation of a sizable thermal enhancement of magnetization is put forward for uniaxial ferromagnetic nanoparticles that are placed in a rotating magnetic field. We elucidate the nature of this phenomenon and evaluate the resonant frequency dependence of the induced magnetization. Moreover, we reveal the role of magnetic dipolar interactions, point out potential applications, and reason the feasibility of an experimental observation of this effect.
