摘要： 在流体中考虑铁磁纳米粒子的确定性旋转。 研究由圆偏振和线偏振交变磁场驱动的纳米粒子的粘性摩擦产生的加热现象。 由于这类场的功率损耗取决于纳米粒子诱导运动的特性，所有类型的粒子轨迹都进行了详细描述。 确定了功率损耗与交变场参数的依赖关系。 讨论了获得最大加热效率的最佳条件。 分析了静态场对加热增强的影响。 所得结果适用于磁流体热疗癌症治疗中加热的描述，当所用粒子的尺寸为几十纳米时。 显示英文摘要

摘要： The deterministic rotation of a ferromagnetic nanoparticle in a fluid is considered. The heating arising from viscous friction of a nanoparticle driven by circularly and linearly polarized alternating magnetic fields is investigated. Since the power loss of such fields depends on the character of the induced motion of a nanoparticle, all types of particle trajectories are described in detail. The dependencies of the power loss on the alternating field parameters are determined. The optimal conditions for obtaining the maximum heating efficiency are discussed. The effect of heating enhancement by a static field is analyzed. The results obtained are actual for the description of heating in the magnetic fluid hyperthermia cancer treatment, when the size of the particles used is a few tens of nanometers.
