Recently, A paper named "Textured Z-type hexaferrites Ba₃Co₂Fe₂₄O₄₁ ceramics with high permeability by reactive templated grain growth method" is published in Journal of the European Ceramic Society (IF:2.947). Miss Panpan Chang is the first and Prof. Hong Wang is the communications writer.

The c-axis oriented Ba₃Co₂Fe₂₄O₄₁ (Co₂Z) ceramic with high permeability was successfully prepared by reactive templated grain growth (RTGG) method using reactive template BaFe₁₂O₁₉ (BaM) and complementary Ba₂Co₂Fe₁₂O₂₂ (Co₂Y). The microstructure and magnetic property of the textured ceramic sample in different orientations were investigated. The sample presents both structural and magnetic anisotropic characteristics. The obtained (0 0 h) textured Co₂Z ceramic exhibits a favorable combination of easy magnetization plane orientation, high initial permeability of 19.0 ± 1.2 (much higher than that from conventional ceramic method (CCM) (μ_i = 12)), and high cut-off frequency (f_r > 1 GHz), indicating the potential for high frequency application in novel electronic devices.
