Magnetoresistive effect element, a magnetic head, and a magnetic reproducing apparatus therewith

摘要

A magnetoresistive effect element is a compound lamination including a first anti-ferromagnetic layer, a first fixed magnetic layer, a tunnel insulation layer, a free magnetic layer, a non-magnetic metal layer, a second fixed magnetic layer, and a second anti-ferromagnetic layer such that a TMR element and a SVMR element are formed, sharing the free magnetic layer.
