      Minority-spin band parameters in a NiMnSb thin film determined by spectral conductivity 

      Grigorescu, C. E. A.; Trodahl, H. J.; Strickland, N. M.; Bittar, A.; Manea, S. A.; Giapintzakis, John; Monnereau, O.; Notonier, R.; Kennedy, V. J. (2004)
      NiMnSb is expected to be a ferromagnetic half metal, an expectation that is based in part on band structure calculations. Here we report optical conductivity studies of the band structure for a film prepared by pulsed laser ...

      Stoichiometry issues in pulsed laser deposition of the ferromagnetic alloy NiMnSb 

      Grigorescu, C. E. A.; Monnereau, O.; Manea, S. A.; Notonier, R.; Klini, A.; Zorba, V.; Manousaki, A.; Giapintzakis, John; Fotakis, C. (Affiliation: NIRDO, BucharestAffiliation: MADIREL, Univ.

Structure and Laser, Heraklion, Crete, GreeceCorrespondence Address: Grigorescu, C.E.A.NIRDO, Bucharest, 2002)
      We report on the reproducible growth of stoichiometric thin films of ferromagnetic intermetallic compound NiMnSb by pulsed laser deposition (PLD) on various substrates. The films are grown at moderate temperature (around ...

      Surface particularities in pulsed laser ablation/deposition of the ferromagnetic alloy NiMnSb 

      Grigorescu, C. E. A.; Manea, S. A.; Mitrea, M.; Monnereau, O.; Notonier, R.; Tortet, L.; Keschawarz, R.; Giapintzakis, John; Klini, A.; Zorba, V.; Androulakis, J.; Fotakis, C. (2003)
      In this work we investigate the surface morphology and stoichiometry of the ablated targets employed with pulsed laser deposition (PLD) of thin films of the ferromagnetic half-Heusler alloy NiMnSb. The NiMnSb targets were: ...
