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 ...
