Hall effect Scientific  

/ hôl /

1. A phenomenon that occurs when an electric current moving through a conductor is exposed to an external magnetic field applied at a right angle, in which an electric potential develops in the conductor at a right angle to both the direction of current and the magnetic field. The Hall effect is a direct result of Lorentz forces acting on the charges in the current, and is named after physicist Edwin Herbert Hall (1855–1938).

Example Sentences

In collaboration with colleagues in Columbia's physics department, their graphene displayed striking evidence for the fractional quantum Hall effect under magnetic fields, a quantum phenomenon that had previously only been observed in ultrahigh-quality, two-dimensional electrical systems.

"It is fascinating to think what this novel system can bring us in the future. The 1D superconductivity presents an alternative path towards realising topological quasiparticles combining the quantum Hall effect and superconductivity," concludes Dr Xin.

From Science Daily

They detected and magnetically controlled a non-Ohmic conduction termed the second-order Hall effect, where voltage responds orthogonally and quadratically to the applied electric current.

From Science Daily

"Our second-order Hall effect arises from the quantum-metric structure that couples with the specific magnetic texture at the Mn3Sn/Pt interface. Hence, we can flexibly manipulate the quantum metric by modifying the magnetic structure of the material through spintronic approaches and verify such manipulation in the magnetic control of the second-order Hall effect," explained Jiahao Han, the lead author of this study.

From Science Daily

It´s based on a quantum phenomenon called Quantum Anomalous Hall effect.
