Webcrystalline anisotropy energy (MAE) with high Curie temperature. MAE is another important parameter, which defines the hardness with respect to the microscopic characteristics. In spite of the highest uniaxial MAE of ~24.2 MJ/m3 (12.96 meV/f.u.) in SmCo 5, 1 the world market is dominated by the Nd 2Fe 14B (MAE of ~4.9 MJ/m 3) … WebMar 15, 2024 · Magneto-crystalline anisotropy (MAE) is the energy required per unit volume to change the orientation of the magnetic moments under the external magnetic field, which is required to achieve the high coercivity in the permanent magnets.
WebMay 3, 2024 · This is a consequence of magneto-crystalline anisotropy from spin–orbit interactions, which apparently have a stronger effect in the more anisotropic film limit 33,41,45. WebSingle-crystal calcium fluoride (CaF"2) is the most suitable material for a highly efficient optical micro-resonator. The CaF"2 resonator can only be manufactured by ultra-precision machining processes, because its crystal anisotropy does not allow the application of chemical etching.
WebNov 8, 2024 · Permanent magnet materials require a high uniaxial magneto-crystalline anisotropy. Exchange coupling between small crystallites with easy-plane anisotropy induces an effective uniaxial anisotropy if arranged accordingly. Nanostructuring of materials with easy-plane anisotropy is an alternative way to create hard-magnetic … WebJul 3, 2024 · For this purpose, we prepared Co x Fe 3−x O 4 NPs, with x = 0–1 in steps of 0.2, from soft magnetic (Fe 3 O 4) to hard magnetic (CoFe 2 O 4) ferrite, with a significant variation of the magnetic anisotropy. The phase purity and the formation of crystalline NPs with a spinel structure were confirmed through Rietveld refinement.
