IMPROVED MAGNETORESISTIVE TRANSDUCER

摘要

A magnetoresistive transducer includes at least one magnetoresistive element (15) having a transverse easy axis. The use of a transverse easy axis prevents magnetic domains from forming in the magnetoresistive elements and results in a noise-free device. Various techniques for producing a transverse easy axis include the use of stress, and a magnetostrictive material, during the formation of the MR element to orient the anisotropy of the element transverse to the element, formation of the element in the presence of a magnetic field, high temperature anneal of the element, or any other method of forming the element with a prebiased state.
