摘要
A free layer of an MR element incorporates a first layer, a second layer, a third layer, a fourth layer, a fifth layer and a sixth layer that are stacked in this order on a nonmagnetic conductive layer. The absolute value of magnetostriction constant of the free layer is 1×10−6 or smaller. The coercivity of the free layer is 20×79.6 A/m or smaller. The first layer is made of an alloy containing ‘a’ atomic percent cobalt and (100−a) atomic percent iron wherein ‘a’ falls within a range of 20 to 50 inclusive. The second layer is made of an alloy containing ‘b’ atomic percent cobalt and (100−b) atomic percent iron wherein ‘b’ falls within a range of 70 to 90 inclusive. In addition, oxidation treatment is given to a surface of the second layer farther from the first layer.
