Abstract

Sm3+-substituted W-type Ba1-xSmxMg2.Fe15.6Co0.4O27 (x=0.00 to 0.30 with steps of 0.06) ferrites were prepared by a solid-state method. The XRD results indicated that the single W-type ferrite structure can be obtained for the specimens with x≤0.18, while the impurity phases appeared for x≤0.18. The lattice parametersa and c, the cell volume (Vcell) and the average grain size (Da) decrease with the increase of x. From the FE-SEM images, it can be found that all the samples exhibited a hexagonal plate shape. The saturation magnetization and the initial magnetic permeability first increased with x from 0.0 to 0.12, but then decreased withx>0.12. The coercivity kept increasing with the increase of x gradually.


Keywords: W-type ferrite, Solid-state method, Magnetic properties, Permeability.
