Restwiderstandsverhältnis, Durchmesser-Effekt und Stromabhängigkeit des Widerstandsverhältnisses von zonengeschmolzenem Wolfram bei tiefen Temperaturen
Das Widerstandsverhaltnis r(T) = R(T)/R(273) elektronenstrahlzonengereinigter Wolframeinkristalle wird zwischen 1,4 und 27 °K untersucht. Die extrapolierten Restwiderstandsverhaltnisse r0 = R(0)/R(273) liegen zwischen 3 und 65 · 10−6. Die Abweichungen von der Matthiessenschen Regel, die nicht erfullt ist, werden ermittelt. Im gesamten Temperaturbereich erhoht das Eigenmagnetfeld des Probenstromes den Widerstand der Wolframproben. Die Abhangigkeit des Widerstandsverhaltnisses vom Durchmesser der Proben wurde zwischen 14 und 20 °K gemessen und daraus das Produkt aus freier Weglange λ und Widerstandsverhaltnis des kompakten Materials r∞ berechnet (r∞ · λ = 3,8 · 10−6 cm).
The resistance ratio r(T) = R(T)/R(273) of electron-beam zone-refined tungsten single crystals is studied over the temperature range 1.4 to 27 °K. The extrapolated residual resistance ratios r0 = R(0)/R(273) range from 3 to 65 · 10−6. The results are compared with Matthiessen's rule. Throughout the whole temperature range, the resistivity of the samples is found to be increased by the magnetic field of the sample current. Between 14 and 20 °K, the dependence of the resistivity ratio on the diameter of the samples is measured, and the product of the mean free path λ and the bulk resistance ratio r∞ (r∞ · λ = 3.8 × 10−6 cm) is calculated in terms of the experimental results.
