Cations distribution and magnetic properties of Co–Zr doped BaCo x Zr x Fe (12−2x) O 19 prepared via citrate precursor sol–gel route

Effect of Fuel on the Synthesis, Structural, and Magnetic Properties of M-Type Hexagonal SrFe12O19 Nanoparticles

“…For uniformly distributed Fe 3+ in these sites, these sites should occupy 50:17:17:8:8 area corresponding to 12k, 4f 1 , 4f 2 , 2a, and 2b sub-lattices, respectively [30][31][32][33][34][35].…”

Study on structural and magnetic properties of nanosized M-type Ba-hexaferrites synthesized by urea assisted citrate precursor route

“…But after x = 0.8, dopants are substituted at 12k sites which is parallel to applied field. The small fall in M S $ 5% registered for [18,28,48,49]. For undoped sample, the curve exhibits a large slope at high field suggesting unsaturated state.…”

“…The S ⁄ and R ⁄ blocks have equivalent atomic arrangements, but are rotated at 180°with respect to S and R blocks around c-axis. S or S ⁄ block consists of two O 2À layers; while R or R ⁄ block contains three O 2À layers, with one oxygen site in the middle layer substituted by Ba 2+ ion [18,28,41]. There are 64 ions per unit cell on 11 sites of different symmetry.…”

“…Various processing techniques have been employed to synthesize hexagonal ferrites, especially by standard ceramic [20,21] or mechanochemical processing [22] and various wet methods [18,[23][24][25][26][27][28][29][30][31]. But their correlation between the dopant substitution and effect on their structural as well as magnetic properties are still seemed a point of explanation.…”

Excellent microwave absorption properties by tuned electromagnetic parameters in polyaniline-coated Ba0.9La0.1Fe11.9Ni0.1O19/reduced graphene oxide nanocomposites

“…24 In the FTIR spectrum of BF/RGO/ PANI nanocomposites, the characteristic peaks at 1562 cm View Article Online C-N stretching for the benzenoid ring, the peak at 1110 cm À1 is attributed to the aromatic C-H in-plane bending mode and the peak at 797 cm À1 is associated with the C-H of the benzenoid unit. 26 Therefore, from the FTIR analysis we can deduce the successful formation of the prepared nanocomposites.…”
