Spin-valve thin-film magnetic element provided with single free magnetic layer
A spin-valve thin-film magnetic element has a composite provided on a substrate. The composite includes an antiferromagnetic layer, a pinned magnetic layer, a nonmagnetic conductive layer, and a free magnetic layer. The composite also has bias layers and electrode layers on two sides thereof. The hard bias layers magnetize the free magnetic layer in a direction perpendicular to the pinned magnetic layer. The free magnetic layer is composed of a single CoFe-based alloy. The average crystal grain diameter in the free magnetic layer is 150 angstroms or less in the planar direction of the free magnetic layer. The volume of the crystal grains in which the <111> direction is predominantly oriented in a direction perpendicular to the planar direction of the free magnetic layer is 50 percent or less of the free magnetic layer.
