  • Strong textured SmCo5 nanoflakes with ultrahigh coercivity

    Strong textured SmCo5 nanoflakes with ultrahigh coercivity

    Aug 14, 2015 Lately, the surfactant-assisted ball milling (SABM) method has been found efficient in the textured nanostructured rare earth compound synthesis 4. However, the texture degree and coercivity still have much room for improvement. It is known that most of the magnetic materials are brittle when the size of the particles is large, and with the ...

    Anisotropic Sm Co Fe nanoparticles by surfactant

    Abstract. Magnetically hard Sm2 (Co0.8 Fe0.2) 17 and SmCo5 nanoparticles have been produced by using surfactant-assisted low- and high-energy ball milling techniques. Surfactants prevent the rewelding of the crashed particles during the milling process. Heptane was used as the milling medium and oleic acid as the surfactant.

    Sm2Co17 nanoparticles synthesized by surfactant assisted

    Oct 25, 2012 Surfactant-assisted high energy ball milling (HEBM) is usually used for the preparation of separated Sm–Co-based hard nanoparticles. In this study, Sm 2 Co 17 hard nanoparticles have been synthesized by the surfactant-assisted HEBM SmCo 5 precursors. Phases, microstructure, particle sizes and magnetic properties of the synthesized Sm 2 Co 17 ...

    Magnetic nanoparticles produced by surfactant assisted

    Magnetic nanoparticles produced by surfactant-assisted ball milling. Nanoparticles of Fe, Co, FeCo, SmCo, and NdFeB systems with sizes smaller than 30 nm and narrow size distribution have been successfully prepared by ball milling in the presence of surfactants and organic carrier liquid. It has been observed that the nanoparticles prepared by ...

    Anisotropic bonded magnets fabricated via surfactant

    Anisotropic bonded magnets are fabricated by surfactant-assisted ball milling in a magnetic field and magnetic field alignment of the milled chip-like nanoparticles of the Sm–Co and Nd–Fe–B materials. It is found that the application of magnetic fields during the ball milling

  • Magnetic properties of Ba ferrite powders prepared by

    Magnetic properties of Ba ferrite powders prepared by

    Magnetic properties of Ba-ferrite powders processed by a novel method: surfactant assisted low energy ball milling, are discussed. By using cationic and anionic surfactants at pH values above and below the point of zero charge of the oxide surface, some remarkable changes in magnetic properties of the milled material are produced. Vibrating sample magnetometry (VSM) and ferromagnetic resonance ...

    Processing and characterization of Nd2Fe14B microparticles

    Jul 25, 2018 The synthesis of hard magnetic nanoparticles based on the Nd 2 Fe 14 B system has been studied by means of surfactant-assisted ball milling technique. The XRD results show that, in the range of milling time employed (5, 10 and 20 h), a majority of Nd 2 Fe 14 B phase was detected in the nanoparticles, indicating that no oxidation took place during milling. . M ssbauer spectra were fitted …
