    • High thermal stability of carbon-coated L10-FePt nanoparticles prepared by salt-matrix annealing 

      Nandwana, Vikas; Rong, Chuan-Bing; Poudyal, Narayan; Chaubey, Girija S.; Liu, Yuzi; Wu, Y.Q.; Kramer, M.J.; Kozlov, M.E.; Baughman, Ray H.; Liu, J. Ping (AIP, 2008)
      Monodisperse L10-FePt nanoparticles with size ranging from 3 to 8 nm were prepared by the salt-matrix annealing method. It was observed that the annealed particles have high thermal stability—no sintering occurred even ...

    • Phase Transformation and Magnetic Hardening in Isolated FePt Nanoparticles 

      Liu, J. Ping; Rong, Chuan-Bing; Nandwana, Vikas; Poudyal, Narayan; Chaubey, Girija S. (IEEE XploreIEEEDepartment of Physics, The University of Texas at Arlington, 2009-07)
      Isolated monodisperseL10 FePt nanoparticles coated by carbon were obtained by adding enough surfactants that decomposed into carbon after the chemical synthesis and postannealing of the A1 FePt nanoparticles. The effect ...

    • Structural phase transition and ferromagnetism in monodisperse 3 nm FePt particles 

      Nandwana, Vikas; Rong, Chuan-Bing; Chaubey, Girija S.; Skomski, R; Wu, Y.Q.; Kramer, M.J.; Liu, J. Ping (AIP, 2007)
      FePt nanoparticles with a size of 3 nm and thermally stable room-temperature ferromagnetism are investigated. The monodisperse nanoparticles were prepared by chemical synthesis and a salt-matrix annealing technique. ...
