    • Do thermal fluctuations influence the recoil loops of nanocomposite magnets? 

      Rong, Chuan-Bing; Liu, Yuzi; Liu, J. Ping (American Institute of PhysicsDepartment of Physics, The University of Texas at Arlington, 2008-07-11)
      An exchange-coupled FePt/Fe3Pt nanocomposite system with well defined hard/soft two-phase morphology was prepared by reducing chemically synthesized FePt/Fe3O4 bimagnetic nanoparticles. It was interesting to observe that ...

    • 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 ...
