BaFe12-xCrxO19 (x = 0.0, 0.1, 0.2, 0.3, and 0.4) ferrite ceramics were prepared by a sol-gel method using spruce sapwoods as the templates. The prepared materials were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and a magnetic property measurement system (MPMS). The prepared materials maintained a multilayer wall structure of spruce sapwoods. All samples presen...

CoY hexaferrite-filled PEEK (poly ethyl ether ketone) compositeswere synthesized to characterize the effect of hexaferrites on their dielectric, magnetic and thermal properties for wireless sensing and communication applications. Fillers were synthesized from solid-state reaction route and blendedwith the thermoplastic polymermatrix.XRDwas used to study the phase purity of the synthesised fille...

Barium hexaferrite (BaHF) with the chemical formula BaFe12O19 is a hard magnetic material and has high magnetic anisotropy field (MAF), 17 kOe. The easy direction of magnetization corresponds to the crystallographic c-axis and BaHF particles orient in this direction when are exposed to an external magnetic field. Because of the high MAF, a ferromagnetic resonant frequency appears from 45 to 50 ...

BaFe12O19 (BaM) hexaferrite was synthesised through the coprecipitation method. BaFe12O19-activated charcoal-chitosan (BaM-AC-CS) composite ultra-sonication assisted water in oil microemulsion Morphology of BaM hexaferrite, activated charcoal, and BaM-AC-CS powder evaluated using FESEM. The average particle size 60 µm. exhibited a surface area 41.5 m2 g ?1 pore volume 0.041 cm3 g?1. magnetic be...
