A hexagonal ferrite-based millimeter wave notch filter was demonstrated. The filter consists of an M-type BaFe12O19 BaM slab sitting on top of a stripline. The band-stop filtering response originates from the ferromagnetic resonance absorption in the BaM slab. The BaM slab has an in-plane uniaxial anisotropy field of 17 kOe. This anisotropy field facilitates the operation of the filter beyond 5...

the composite powders of barium-magnesium ferrite were prepared using sol-gel auto-combustion and microwave methods. the crystal structure and the shape of nanocomposites have been compared. x-ray diffraction (xrd), scanning electron microscope (sem) and vibrating sample magnetometer (vsm) were used to investigate the structural, morphological and magnetic properties of nanopowder. the formatio...

nanocrystalline particles of barium hexaferrite has been prepared by the sol–gel auto- combustion method using iron and barium nitrate with a ba:fe molar ratio of 1:10. the effect of fuel such as citric acid and aspartic acid was investigated on the structure and magnetic properties of nanoparticles. the results revealed that the formation of barium hexaferritefine particles is influenced by mo...

Synergistically regulating carrier and phonon transport on the nanoscale is extremely difficult for all thermoelectric (TE) materials without cage structures. Herein BaFe12O19/Bi2Te25Se0.5 thermoelectromagnetic nanocomposites are designed synthesized as a benchmarking example to simultaneously tailor properties nanoscale. A magneto-trapped effect induced by BaFe12O19 hard-magnetic nanoparticles...

In this communication we present a new sol–gel route to obtain high quality BaFe12O19 thin films. X-ray analysis confirmed the crystal structure with a crystal size of 32 nm. Atomic force microscopy images determined the film thickness to be around 250 nm and a roughness factor of less than 40 nm where the grain size averaged around 150 nm. SQUID magnetometer data shows a magnetic behavior simi...
