Abstract
In this work, M-type strontium ferrite LuxSrFe12−xO19 (x = 0, 0.2, 0.4, 0.6) was prepared using a precursor chemical co-precipitation method. The structures, morphologies, and elemental compositions of the samples were analyzed using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The magnetic properties of the prepared samples were determined using a vibrating sample magnetometer (VSM). XRD peaks revealed its crystalline nature, exhibiting a hexagonal single-phase magnetic spinel crystal structure. SEM micrographs displayed regular hexagonal grain structures, with the grain size gradually decreasing with increasing Lu3+ ions content. VSM analysis confirmed that LuxSrFe12−xO19 is essentially a hard magnetic material with significant coercivity, and the saturation magnetization and remanent magnetization exhibited a trend of initially decreasing and then increasing with the increasing Lu3+ ions content. Furthermore, Lu3+ ions substituted SrFe12O19 ferrites find wide applications in magnetic recording and memory devices.
