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 ...

Possible use of the half-Hausler alloy NiMnSb in spintronics: Synthesis and physical properties of arc melted NiMnSb and of NiMnSb thin films grown on InSb by pulsed laser deposition
Gardelis, S.; Androulakis, J.; Monnereau, O.; Buckle, P. D.; Giapintzakis, John (2005)We report the growth of single-phase, stoichiometric polycrystalline thin films of the half-Heusler ferromagnet NiMnSb, predicted to be half-metallic, on single crystal (100) InSb substrates heated at 200 °C by pulsed laser ...

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: ...
