Ferromagnetic nanomaterials are of particular interest, because at nanoscale a crystallite can exhibit a single magnetic domain. These nanomaterials therefore exhibit different magnetic properties as compared to bulk. Recently, barium ferrite has gained importance due to its potential use in magnetic recording and in microwave devices. Barium ferrite nanoparticles are prepared by the citrate pr...

Many studies have been conducted on Spinel, Garnet, and Hexa-ferrites in single multi-doped concentrations. This article is an attempt to review the researcher's work Ca, Ba, Sr hexaferrite by substituting a variety of various ions such as Al, La, Sn, Zr, Co, Cr, Ir. paper investigates M-type (Ca, Sr, Ba) with space group P63/mmc that were synthesized using techniques characterized XRD for crys...

The influences of anionic sodium dodecylsulfate (SDS) and cationic Hexadecyltrimethylammonium bromide (HTAB) surfactants on the incorporation and distribution of barium hexaferrite nanoparticles in the electrodeposited CoFe-BaFe12O19 composite thin films were studied. Sulphate bathes with natural pH containing 0 to 2 g/L surfactants were used for electroplating at room temperature. Field emissi...

The microscopic mechanism of the occurrence ferroelectric properties in M-type barium hexaferrites is investigated by experimental and first-principle computation methods. analysis magnetic, X-ray, Mössbauer measurements BaFe12O19 samples ascertains correlation between thermal factor process annealing their functional properties. remnant polarization at room temperature contradicts description ...

Tape casting technics were used to realize a screen with continuous change in characteristics. Different hexaferrite compositions owned by the Ba3C02-~Zn~Fe24041 (Z) family were synthetized by coprecipitation method and calcined at 1200 "C in air. Then a slurry containing this powder is slip casted using tape casting. The tapes are dried under magnetic fied in order to orient the magnetic plate...

In this study, strontium hexaferrite nanoparticles synthesized by sol–gel autocombustion method and the effect of high annealing temperature on produced nanoparticle have been studied. Powders were annealed at 1,000 1,300°C. Structural properties powders analyzed X-ray diffraction (XRD). Hexagonal structure shape SrFe12O19 from field-emission scanning electron microscope transmission figures. F...
