Abstract
Composite galvanomagnetic devices having a desired combination of properties in specific temperature ranges and magnetic field ranges and so combined that desired properties are provided over an extended temperature and magnetic field range. In practice this can be accomplished with a single die with layers of different properties. Particularly, the present invention addresses this method as related to magnetoresitors and Hall plates.
