Theory of Electrical Resistivity
Physical Review A, 1972A new general expression for the electrical resistivity of a substance is obtained with the help of projection techniques with the Liouville equation as the point of departure. No many-body detail is sacrificed and the "${\ensuremath{\lambda}}^{2}t$ limit" is not invoked. The first-order result in a perturbation expansion in orders of the scattering is

Electrical Resistivity of Scandium
Journal of Applied Physics, 1963Electrical resistivity of polycrystalline scandium has been studied between 1.38° and 358.8°K. The measurements show a step-type anomaly in the resistivity between 4 and 5°K and possibly a very small minimum at 9.5°K. Considerable hysteresis in the electrical resistivity exists at low temperatures, depending upon the previous thermal history of the ...

Anisotropy of electrical resistivities in electrical sheets
Journal of Magnetism and Magnetic Materials, 1985Abstract One of the basic parameters of all electric devices is their efficiency which depends on the losses in the magnetic cores. These are constructed mainly of cold-rolled electrical sheets which display a flat directional anisotropy resulting from a strong texture, disordering of lattice as well as from strip packing of non-metallic instrusions.

Electrical resistivity of voids
Journal of Physics F: Metal Physics, 1973The electrical resistivity of spherical clusters of vacancies (voids) in the three simple metals sodium, magnesium and aluminium has been calculated by two different methods, one based on phase shift scattering and the other on pseudopotentials. In the phase shift method the clusters were represented by a spherical potential well, whose radius was ...

, 2011 The electrical resistance of ferromagnetics
Proceedings of the Physical Society, 1937The resistance of nickel and iron is measured between 20 and 1200° k. From the measurements it is concluded that: (1) the kink in the {resistance, temperature} curve at the Curie point is sharp to within a small fraction of a degree; (2) above the Curie point the {resistance, temperature} curve is concave to the T axis as in a paramagnetic metal such ...
