|Abstract:||Electromigration (EM) in giant magnetoresistance (GMR) spin valve read sensors under pulsed magnetic field of 50200Oe with different duty factors was experimentally studied to explore the physical mechanisms of EM failures during sensor retrieving operation. It was found that the GMR effect, which causes the temperature rise and fall due to the change in resistance, is dominantly responsible for the acceleration of EM failures at a small retrieving field (50Oe). A theoretical model incorporating the GMR and Hall effects was proposed to interpret the EM failure characteristics. The physical validity of this proposed model is confirmed by the comparisons with experimental results. © 2012 IOP Publishing Ltd.|
