In a ferromagnetic metal the Hall voltage depends on the arrangement of magnetic domains. During operation it will be necessary to apply a magnetic field to the sample and to pass a current through the sample. Therefore, the magnetic and electrical properties of the materials used in the construction of the mechanism will have to be considered in the design. There are several possible avenues of approach. Design group is limited to two people.
Schematic reading is required.
Software knowledge is required. The growth of thin films in a vacuum system often requires deposition on substrates according to special patterns. Certain films must have a given pattern, other films must have a different pattern. These pattern are created by covering the substrate with suitable masks. It is very desirable to be able to change the masks on the substrate without breaking the vacuum, i.e., without opening the vacuum system and thereby exposing the films already deposited to atmospheric pressure.
