The theoretical expression deduced by Mola and Heras from the Mayadas–Shatzkes model of monocrystalline thin film resistivity is approximated assuming that the Sommerfeld relation is valid and introducing corrections to the Matthiessen's rule.The approximate expression of kρf /ρ0deviates from less than 6% in the 0.01–2 k-range, 0–0.5p-range and 0.1–0.62r-range.

Matthiessen’S Rule

Matthiessen's rule has been tested by, determining the slopes of the electrical resistivity-temperature curves for wires of eight common metals and alloys in various states of deformation by wire-drawing. The results show that the slope is independent of deformation, i.e. the rule is true, to within 0�5 per cent. for nickel, copper (two purities), iron, and 80/20 brass, and to within 1 per cent. for aluminium. However, for 75/25 brass and an aluminium bronze, deformations corresponding to logarithmic strains of 2�3 decrease the slopes by 1 and 3 per cent. respectively. As an explanation of this behaviour, it is suggested that deformation causes an increase in the characteristic temperature.

Matthiessen’S Rule

The relationship between the real and ideal resistance functions (RT/R273) has been examined for a wide variety of specimens of thermometric platinum over the range 0–900° K. An attempt was made to relate these two functions by using Matthiessen's rule in addition to Kohler's theoretical expression for the deviation from Matthiessen's rule. It was found that Kohler's relation did not apply for most specimens of thermometric platinum; however, in the restricted range 20–90° K, it appeared to hold fairly well for about 17 of the 65 resistors examined.Values for the ideal resistance function have been determined by extrapolating the measured resistance values of a large number of platinum resistance thermometers. In the range 10–90° K a special method of extrapolation has been used which appears to give greater accuracy than previously attained. Also, methods for estimating the residual resistance ratio (at 0° K) from measurements at higher temperatures are discussed.The results of this investigation have been applied to the practical problem of extending the present platinum resistance temperature scale below 90.19° K. To this end, a somewhat different method for interpolating the real resistance function between a number of fixed calibration temperatures has been outlined and compared with earlier methods.

The Ideal

We have calculated the electrical resistivity of several dilute aluminum based alloys for which experimental data exist on the deviation from Matthiessen's rule(DMR). We take account of the anisotropy in the ideal (pure metal) scattering and its modification on adding impurities. This is a major source of DMR. In addition, we compute the effect of inelastic impurity scattering, interference between impurity and ideal scattering, Debye–Waller factors, and also the effect of mass changes on the alloy resistivity. While some of these mechanisms for DMR can be of importance under specific conditions, they should be included only after the major effect of anisotropy in the ideal scattering has been properly treated.
