This article aims to study the core losses behavior at high frequency (MHz range) with superimposed dc bias in ferrite. Inductive compensation method is employed measurement circuit reduce sensitivity phase errors. An addition proposed this work make easier generation. Furthermore, a detailed accuracy consideration also discussed. The tested MnZn ferrite has nominal relative permeability of 1500 and 800, which was from 500 kHz 3 MHz. results are explained thoroughly three controlling...
According to the classical laws of magnetism, shape magnetically soft objects limits effective susceptibility. For example, spherical magnets cannot display an susceptibility larger than 3. Although true for macroscopic multi-domain magnetic materials, we show that nanoparticles in a single-domain state do not suffer from this limitation. We find differences between demagnetisation factors along principal axes are relevant and can influence particles, but limit as case particles. validate...
Correct estimation of the heating power magnetic nanoparticles is important for hyperthermia treatment. This work investigates impact sample insulation in AC calorimetry. We show that temperature increase can lead to systematic errors when estimating by corrected slope method. The arise if environment kept fixed at its initial data analysis. To correct this, we propose use a local difference between and environment.
According to the laws of magnetism, shape magnetically soft objects limits effective susceptibility. For example, spherical magnets cannot display an susceptibility larger than 3. Although true for macroscopic multi-domain magnetic materials, we show that nanoparticles in a single-domain state do not suffer from this limitation. This is consequence particle moment being forced saturation by predominance exchange forces, and only allowed rotate coherently response thermal and/or applied...
