The double differential magneto resistor assembly consists of two pairs of magneto

resistors, (L-type InSb/NiSb semiconductor resistors whose resistance value can be

magnetically controlled), which are fixed to a ferrite substrate. Contact to the magneto

resistors is achieved using a copper/polyimide carrier film known as Micropack.

The basic resistance of each of the magnetic resistors is 80

Ω. The two series coupled

pairs of magnetic resistors are actuated by an external magnetic field or can be biased

by a permanent magnet and actuated by a soft iron target.
