- We present results of in situ temperature measurements of resistivity for some amorphous or partially crystalline Heusler alloy films: $Co_{2}CrAl$, $Co_{2}MnGa$ and off-stoichiometric $Ni_{2}Mn_{1+x}Sn_{x}$, $Ni_{2}Mn_{1-x}Ga_{x}$ that are known to exhibit half-metallic properties and martensitic transformations, respectively. From ρ vs. T characteristics we distinguish various stages of chemical and structural ordering in the films. They appear to be quite distinct in both systems investigated. The resistivity results are compared with magnetic characteristics for $Co_{2}MnGa$ with a high Curie temperature.
