The magnetoresistive recording heads (MRH) as a magnetic field vector detector

A pair of monolithic ferromagnetic thin-film magnetoresistive recording head, MRH, (also referred to as the Chevron) has been investigated as a detector of magnetic field vector. Its application in the detection of magnetic fields in localised areas above the insulating coating on magnetized sheet s...
