In the work investigated influence of plasma treatment conditions on structural-phase composition and magnetic properties barium hexaferrite films (0001) BaFe12O19 C-sapphire. Two modes were used: with a weight average temperature 4÷5kK 8÷10kK. It has been shown that obtained at low have pronounced anisotropy saturation magnetization 42 emu/g. The high weak anisotropy, but higher value 62 All c...

Ceramic–polymer paste-injection molding is demonstrated as a facile fabrication route for barium hexaferrite magnets. Interestingly, these low-density (1.90–2.35 g/cm3) magnets exhibit substantial coercivity of 3868–4002 Oe. When ceramic paste without polymeric additives used, reduced and slightly increased magnetizations are obtained from magnet with the density 2.55 g/cm3. Their also higher t...

Abstract The effect is reported of substituting the non-magnetic Zn 2+ cations with magnetic Ni cations, and Fe 3+ Al in Ba 0.5 Sr 1.5 11.92 0.08 O 22 on resulting properties. Y-type hexaferrite powders were synthesized by citric acid sol-gel auto-combustion, followed appropriate thermal annealing. saturation magnetization values ( M s ) a field 50 kOe 36 emu/g 30 at 4.2 K 300 K, respectively. ...
