... The SD grains behave quite differently to MD grains. Under the influence of an external field the magnetisation of an SD grain may be deflected by a small amount (as depicted in Figure 3d), but it is not free to swing away from the ‘easyaxis’ (usually the long axis) of the grain. Under the influence of ...

Hall effect
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.The Hall coefficient is defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field. It is a characteristic of the material from which the conductor is made, since its value depends on the type, number, and properties of the charge carriers that constitute the current.
