The dR/R ratios of TMR and GMR devices, having a FeCo/NiFe type of free layer, have been significantly increased by inserting a suitable surfactant layer within (as opposed to above or below) the free layer. Our preferred surfactant material has been oxygen but similar-acting materials could be substituted. The concept can be applied to GMR CPP, CIP, and CCP sensor designs. |
