Fabrication and micromagnetic modeling of barium hexaferrite thin films by RF magnetron sputtering

Results in Physics, 2018
The synthesis and characterization of thin M-type barium hexaferrite (BaFe12O19 or BaM) films on silicon are reported. Multilayer in situ technique was employed to anneal the films at 850–900 °C for 10 min.

Electromagnetic Properties of Substituted Barium Hexaferrites

Acta Physica Polonica A, 2008
Substituted M-type ferrite BaFe12−2x(Me1Me2)xO19, 0 ≤ x ≤ 0.6 was prepared by both mechanical alloying and precursor method, where Me1 = Co, Ni, Zn, Sn and Me2 =Ru, Ti, Zr, Sn. Magnetic phase purity, change of saturation polarization, Curie temperature, coercivity and magnetic susceptibility was studied as function of x.
