Improvement in magnetic properties of La substituted BaFe12O19 particles prepared with an unusually low Fe/Ba molar ratio

The Effect of Condensation on the Morphology and Magnetic Properties of Modified Barium Hexaferrite (BaFe12O19)

“…Fortunately, this phase can be removed by HCl etching [47]. In this way, Sozeri et al very recently succeed to synthesize high purity and high quality barium hexaferrite samples with an initial Fe/Ba molar ratio of 2:1 [48]. XRD pattern of sample Z1 also has a low intensity peak of hematite, fraction of which is very low and magnetization of this sample appeared to be very close to that of bulk sample [49].…”

Electric transport properties study of bulk BaFe12O19 by complex impedance spectroscopy

“…BaM system retains hexagonal structure consists of a closepacked stacking of oxygen layers, with the iron (Fe) atoms distributed within three kinds of octahedral sites (12k, 2a and 4f2), one tetrahedral site (4f1), and one bi-pyramidal site (2b) which are coupled by super exchange interactions through the O 2 À ions [12]. The magnetic and electrical properties of the BaM system depend on the distribution of the cations in octahedral, tetrahedral and bipyramidal sites [12][13][14][15][16][17][18][19][20][21].…”

Structural and Magnetic Properties of BaCo<sub>x</sub>Fe<sub>12x</sub>O<sub>19</sub> (x = 0.2, 0.4, 0.6, &1.0) Nanoferrites Synthesized via Citrate Sol-Gel Method

“…These properties make them well suited materials for numerous applications. They have been extensively used in permanent magnets, high density recording media and magneto optical recording technologies [1][2][3][4]. In addition, they are suitable microwave absorbing materials due to a significant permeability value (>1) [5].…”
