Their structures, morphologies, and magnetic properties were studied using x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), SQUID, and B−H analyzers. Compared to organic and other inorganic composite materials, SrFe<sub>12</sub>O<sub>19</sub> has a higher thermal decomposition temperature. The x-ray diffraction pattern indicates that SrFe<sub>12</sub>O<sub>19</sub> phase was detected in the sample. Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) images show that powdered SrFe<sub>12</sub>O<sub>19</sub> is dispersed on the surfaces and gaps of particles of different sizes. The magnetic analysis results indicate that although SrFe<sub>12</sub>O<sub>19</sub> increases the hysteresis loss of the material, its good insulation reduces eddy current loss. When the content of SrFe<sub>12</sub>O<sub>19</sub> is 2 wt.-%, the magnetic loss is the lowest. The lower magnetic loss and higher thermal decomposition temperature of this composite material make it have a wider range of application prospects.</p>","PeriodicalId":18366,"journal":{"name":"Materialwissenschaft und Werkstofftechnik","volume":"56 2","pages":"251-255"},"PeriodicalIF":1.2,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
