It has been found experimentally that electrical resistivity of a metal is related linearly to temperature according to the formula:
The resistivity (ρ) data for RFeAsO compounds (R=Ce, Pr, Nd, Sm), in the temperature (T) range 35–315K have been analyzed to identify the dominant scattering mechanisms. Close to the room temperature, the system appears to be a metal with low electron density, and the electron–...

Both the extrinsic and the intrinsic part of the temperature dependence of the excess resistivity have been determined for dilute WFe, WCo and WRe alloys, by measuring the resistance as a function of temperature and the thickness of layers removed by electrothinning. In this way the parameters ...

7.On the basis of this theory, we have investigated the temperature dependence of the resistivity in these systems within the one-phonon approximation.根据这个理论我们详细讨论了这类系统电阻率的温度依赖性。 8.The relationship between the temperature dependence of the conductivity and structure of the...
Based on the thermal activation and the spin-polarized tunneling, which depend on temperature range and grain separation, the transport phenomenon is discussed for polycrystalline manganites. By averaging over the distribution of grain separation, we derive a general expression of resistivity which in ...
