SPIN VALVE-TYPE THIN FILM MAGNETIC ELEMENT, MANUFACTURING METHOD THEREFOR AND THIN FILM MAGNETIC HEAD PROVIDED WITH SPIN VALVE-TYPE THIN FILM MAGNETIC ELEMENT

摘要

PROBLEM TO BE SOLVED: To improve an output characteristic in a spin valve-type thin film magnetic element in accordance with the narrowing of a track, to reduce asymmetry, to prevent the occurrence of side reading, to improve the stability of a reproduced waveform, to improve detection sensitivity in the spin valve-type thin film magnetic element and to improve ΔR/R(resistance change rate).;SOLUTION: A laminated body 9 where an antiferromagnetic layer 2, a fixed magnetic layer 3, a non-magnetic conductive layer 4, a free magnetic layer 5, a backed layer (average free process extending layer) B1 and a vertical bias layer 6 are laminated and electrode layers 8 formed on both sides of the laminated body 9 are disposed on a substrate K.;COPYRIGHT: (C)2001,JPO
