    • Hard magnetic FePt nanoparticles by salt-matrix annealing 

      Nandwana, Vikas; Li, Daren; Poudyal, Narayan; Jin, Zhiqiang; Elkins, Kevin Eugene; Liu, J. Ping (AIP, 2006)
      To transfer face-centered-cubic (fcc) FePt nanoparticles to the face-centered-tetragonal (fct) phase with high magnetic anisotropy, heat treatments are necessary. The heat treatments lead to agglomeration and sintering of ...
