Large positive magnetoresistance in nonstoichiometric NiMnSb thin films on silicon
(2004)The transport properties of pulsed-laser-deposited NiMnSb films on silicon as a function of film thickness were discussed. It was found that a low-temperature upturn was observed in the resistivity for film thicknesses of ...

Low-temperature growth of NiMnSb thin films by pulsed-laser deposition
(2002)We report the growth of thin films of the ferromagnetic half-Heusler alloy NiMnSb by pulsed-laser deposition on Si (111) and polycrystalline InAs substrates. Highly crystalline films are grown using low substrate temperatures ...

Magnetic and structural properties of stoichiometric thin Fe 3Si/GaAs(0 0 1) films
(2005)In this study, we report experimental results on the structural and magnetic properties of epitaxial Fe3Si films grown on GaAs(0 0 1) by co-evaporation. X-ray reflectivity shows that relatively smooth interfaces are obtained ...

Measurement of liquid crystal film thickness using interferometry
(2010)Thickness measurements of thin films having thickness less than 1 µm are difficult to obtain by an interferometer. These difficulties arise from the overlap of the fringes from the upper and lower surfaces of the thin ...

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