    • Microstructures and magnetic alignment of L10 FePt nanoparticles 

      Nandwana, Vikas; Kang, Shishou; Shi, Shifan; Jia, Zhiyong; Thompson, G. R.; Nikles, David E.; Harrell, J. W.; Poudyal, Narayan; Liu, J. Ping (AIP, 2009)
      Chemically ordered FePt nanoparticles were obtained by high temperature annealing a mixture of FePt particles with NaCl. After the NaCl was removed with de-ionized water, the transformed FePt nanoparticles were redispersed ...

    • Rapid thermal annealing of FePt nanoparticles 

      Nandwana, Vikas; Yano, Kazuaki; Poudyal, Narayan; Rong, Chuan-Bing; Liu, J. Ping (AIP, 2008-07-01)
      We report a systematic study on rapid thermal annealing (RTA) of FePt nanoparticles. FePt particles with an average size of 8 nm were synthesized by a chemical solution method, and then annealed using RTA and conventional ...
