In this work, we go beyond the mere MLG symmetry requirements on the spontaneous Hall effect by focusing on its microscopic physical mechanisms and chemistry of favorable material candidates, on the magnitude and means to control and detect the effect, and on links to the electronic structure topology.

We investigate the Hall effect by studying the motion of the free electrons along a metallic strip of width l in a constant magnetic field (Figure \(\PageIndex{1}\)). The electrons are moving from left to right, so the magnetic force they experience pushes them to the bottom edge of the strip.
In this video we learn about the Hall effect. This is a quick history and explanation to help you understand some brief theory and how it works.Patreon link:...
The Hall effect allows us to determine that it is negative charges that flow, and not positive charges. Indeed, consider Figure \(\PageIndex{1}\), but replace the electrons with positive charges flowing to the right, which is equivalent as far as analysing the circuit goes.
The Hall effect is used today as a research tool to probe the movement of charges, their drift velocities and densities, and so on, in materials. In 1980, it was discovered that the Hall effect is quantized, an example of quantum behavior in a macroscopic object.
