anomalous Hall effect

anomalous Hall effect

[ə¦näm·ə·ləs ′hȯl i‚fekt]
(electromagnetism)
In a current-carrying conductor in a magnetic field, development of a transverse voltage resulting from the deflection of positive charge carriers (hole states) by the Lorentz force.
The Hall effect in ferromagnetic metals, which arises from the unsymmetrical scattering of conduction electrons at magnetic moments.

He along with others from the Hitachi Cambridge Laboratory and the Universities of Cambridge and Nottingham in the United Kingdom as well as the Academy of Sciences and Charles University in the Czech Republic, is the first to combine the spin-helix state and anomalous Hall effect to create a realistic spin-field-effect transistor (FET) operable at high temperatures, complete with an AND-gate logic device.
Physicists and chemists here chip away at one of the most important problems in physics today, looking at such aspects as the anti-adiabatic theory of the electronic ground state of superconductors, persistent photoconductivity in YBa2Cu3Ox and other high-temperature superconductors, the influence of pair-breaking effects on the long-range odd triplet superconductivity in a ferromagnet/superconductor bilayer, theories of peak effect and anomalous Hall effect for cuprate superconductors, new perspectives on long-standing issues regarding the materials, and an analysis of their microtexture and nanotexture.
Other topics include thermal transients in MgB2 conductors, theories of peak effect and anomalous Hall effect, doping effects on the superconducting properties of bulk and PIT MgB2, optimizing critical current density, and microwave response of ceramic samples.
