Low-temperature electrical resistivity of antiferromagnetic Ce4Pt12Sn25

Low Temperature Resistivity

The temperature dependence of electrical resistivity was measured for three materials: a conductor (copper), a semiconductor (a carbon resistor), and a doped semiconductor (a pn junction). As expected, the resistance of the copper sample decreased with temperature and the resistance of the carbon resistor increased with temperature. The temperature coefficient of resistance of Cu was calculated...

Low-temperature magnetron sputter-deposition, hardness, and electrical resistivity of amorphous and crystalline alumina thin films

Aluminum oxide films were grown by reactive magnetron sputtering. In order to maintain a stable deposition process and high deposition rate, a pulsed direct current bias was applied to the aluminum target and the substrate. An external solenoid was used to form a magnetic trap between the target and the substrate. The influence of substrate temperature, substrate bias, and the magnetic trap on ...

The inversion is the Non-Linear Conjugate Gradient (NLCG) algorithm of Rodi and Mackie (2001). This seeks to efficiently find a model that minimizes the objective function) P(τ χ S 2 m + = where ∑ = = N 1 i 2 i 2 i 2 σ r χ is the sum of the squared data residuals weighted by their variances and P(m) is a structure penalty function. At each choice of trade-off parameter τ, the resulting model m ...

Magnon scattering processes and low temperature resistivity in CMR manganites

Low temperature resistivity of CMR manganites is investigated. At the ground state, conduction electrons are perfectly spin polarized, which is called half-metallic. From one-magnon scattering processes, it is discussed that the resistivity of a half metal as a function of temperature scales as ρ(T )− ρ(0) ∝ T . We take (Nd0.8Tb0.2)0.6Sr0.4MnO3 as an example to compare theory and experiments. T...
