Electrical resistivity and thermopower of single-crystal RNi2B2C „R5Dy, Ho, Er, Tm... magnetic superconductors
The in-plane resistivity r and thermopower S of single crystal RNi2B2C ~R5Dy, Ho, Er, Tm! has been measured from 4 to 300 K. The resistivity is linear in temperature from about 100 to 300 K, but the lowtemperature dependence goes as T with p53.0, 2.6, 2.0, and 1.4, respectively, from Dy to Tm, in comparison to the T behavior previously reported for LuNi2B2C. The thermopower exhibits a region li...
متن کاملMorphology and electrical resistivity of metallic nanostructures
The electrical resistivity r of Au, Al and Cu films prepared by thermal evaporation with thickness range from 3 to 100 nm on glass substrates were studied. The r value was measured and theoretically evaluated by the Fuchs–Sondheimer (F–S), the Mayadas–Shatzkes (M–S), and the combined models. Measured r values in Al films were about seven times minor than for Au and Cu films for the minimum (3 n...
متن کاملSimultaneous Modeling of Thermopower and Electrical Conduction in Olivine
Measurements of conductivity and thermopower as a function of oxygen fugacity (fO2) are used to derive a model for conduction in olivine. Thermopower at 1000– 1200◦C is between 50 and 400 μV/K and has a positive fO2 dependence, and electrical conductivity exhibits approximately a /11 power dependence on fO2 . However, small polarons, considered to be the conducting defect in olivine at these te...
متن کاملElectrical resistivity and tunneling anomalies in CeCuAs2
The compound CeCuAs2 is found to exhibit negative temperature (T) coefficient of electrical resistivity (ρ) under ambient pressure conditions in the entire T-range of investigation (45 mK to 300 K), even in the presence of high magnetic fields. Preliminary tunneling spectroscopic measurements indicate the existence of a psuedo-gap at least at low temperatures, thereby implying that this compoun...
