Effect of sintering time on electronic properties of strontium hexaferrite

Anisotropic properties of Ba1−xSrxFe12O19 single crystals

“…40 Comparable results were recently discovered by Kang et al who could show that an increasing sintering temperature does not only lead to a bigger average crystallite size but also to smaller coercive fields and remanence magnetizations. 41 To quantify the magnetic anisotropy of M-hexaferrites, one can determine the energy required to completely magnetize a sample. Negligible values of remanence and coercivity and additionally the linear μ ( B ) behaviour up to saturation allow a simple calculation: the magnetization energy is given by the area between ordinate axes and the μ ( B ) graph.…”
