      Large positive magnetoresistance in nonstoichiometric NiMnSb thin films on silicon 

      Branford, W. R.; Clowes, S. K.; Syed, M. H.; Bugoslavsky, Y. V.; Gardelis, S.; Androulakis, J.; Giapintzakis, John; Grigorescu, C. E. A.; Berenov, A. V.; Roy, S. B.; Cohen, L. F. (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 ...

      Studies of the tribological and mechanical properties of laminated CrC-SiC coatings produced by r.f. and d.c. sputtering 

      Ziegele, H.; Rebholz, Claus; Voevodin, A. A.; Leyland, A.; Rohde, S. L.; Matthews, A. (1997)
      Multilayer CrC-SiC coatings were produced by both direct current and radio frequency sputtering of Cr and Si targets in an Ar-C2H2 atmosphere. Coatings of constant thickness of about 4 μm, but with the number of layers ...
