摘要

磁化后，FeSiAl/SrFe12O19（SrM）软磁复合材料的磁损耗与磁化前相比大大降低，与外加横向磁场的 FeSiAl 磁粉芯效果类似。实验结果表明，磁化后 SrM 铁氧体提供的内部偏置磁场增大了平均畴尺寸，减少了畴壁数量和畴壁位移，从而有效降低了磁滞损耗。当 SrM 铁氧体的含量为 8.1 wt.-%时，磁损降低了约 50%，整体性能最佳。

Effect of built-in bias field on hysteresis loss of FeSiAl/SrFe12O19 soft magnetic composite Auswirkung eines eingebauten Vorspannungsfeldes auf den Hystereseverlust eines weichmagnetischen Verbundwerkstoffes FeSiAl/SrFe12O19

After magnetization, the magnetic loss of FeSiAl/SrFe₁₂O₁₉ (SrM) soft magnetic composite is greatly reduced compared with that before magnetization, which has similar effect with FeSiAl magnetic powder core with applied external transverse magnetic field. The experimental results show that the internal bias field provided by SrM ferrite after magnetization increases the average domain size, reduces the number of domain walls and the displacement of domain walls, thereby effectively reducing the hysteresis loss. When the content of SrM ferrite is 8.1 wt.-%, the magnetic loss is reduced by about 50 %, and the overall performance is the best.

期刊介绍： Materialwissenschaft und Werkstofftechnik provides fundamental and practical information for those concerned with materials development, manufacture, and testing. Both technical and economic aspects are taken into consideration in order to facilitate choice of the material that best suits the purpose at hand. Review articles summarize new developments and offer fresh insight into the various aspects of the discipline. Recent results regarding material selection, use and testing are described in original articles, which also deal with failure treatment and investigation. Abstracts of new publications from other journals as well as lectures presented at meetings and reports about forthcoming events round off the journal.
