Hall Effect Devices

A wealth of devices which depend on the Hall effect for their operation have been proposed in the last decade. This paper gives the results of a survey of these devices. Original work in this field is included in those sections which describe the circulator, one-piece gyrator, switch, frequency spectrum analyzer, phase discriminator and digital-to-analog encoder. Semiconductor materials are discussed in terms of what type of material is most desirable and how currently available materials limit the usefulness of Hall effect devices.
