Hall Effect for Sensing and Materials Characterization
by from IEEE Spectrum on (#51PFX)
Since the discovery of the Hall effect in 1879 by Edwin
Hall, it has been widely applied in measurements,
particularly in materials characterization and sensing.
Today it is being used to characterize new materials,
enabling the discovery of new phenomena, such as
the quantum Hall effect, spin Hall effect and, more
recently, topological insulators [1]. The Hall effect also
serves as a platform for many device applications,
such as current sensing in the automotive industry,
metrology, non-destructive inspection and testing, and
security screening applications.
