ABSTRACT:
A method of producing a magnetoresistive read transducer with improved longitudinal bias due to high exchange coupling is disclosed. A layer of antiferromagnetic material is sputtered deposited onto a layer of ferromagnetic material in the absence of a magnetic field and at a power density below 0.7 W/cm.sup.2. The layers of ferromagnetic material and antiferromagnetic material are annealed at a low temperature of between 200.degree. C. and 250.degree. C. for between 6 and 26 hours.
