    • Anisotropic nanostructured magnets by magnetic-field-assisted processing 

      Rong, Chuan-Bing; Nguyen, Van Vuong; Liu, J. Ping (American Institute of PhysicsDepartment of Physics, The University of Texas at Arlington, 2010-04-15)
      It has been a great challenge to produce anisotropic nanocrystalline bulk magnets. In this paper, we report our recent work in preparing anisotropic bonded magnets consisting of SmCo5 nanocrystalline particles. The work ...

    • Bulk FePt/Fe3Pt nanocomposite magnets prepared by spark plasma sintering 

      Rong, Chuan-Bing; Nandwana, Vikas; Poudyal, Narayan; Liu, J. Ping; Saito, Tetsuji; Wu, Yaqiao; Kramer, Matthew J. (American Institute of PhysicsDepartment of Physics, The University of Texas at Arlington, 2007-04-27)
      FePt/Fe3Pt bulk nanocomposite magnets have been prepared by the spark plasma sintering of chemically synthesized FePt and Fe3O4 nanoparticles under 100 MPa at 400–600 °C. It was found that the phase transition of the FePt ...

    • Grain boundary contribution to recoil loop openness of exchange-coupled nanocrystalline magnets 

      Rong, Chuan-Bing; Liu, J. Ping (American Institute of PhysicsDepartment of Physics, The University of Texas at Arlington, 2009-04-29)
      It has been well known that recoil loop openness is related to soft-phase presence in exchange-coupled hard-soft nanocomposite magnets. Our study on recoil loop openness of exchange-coupled nanocrystalline magnets (both ...
