摘要：
A CPP spin-valve magnetic head, according to one embodiment includes a ferromagnetic free layer having a bias-point magnetization nominally oriented in a first direction; a ferromagnetic reference layer film having a bias-point magnetization nominally oriented in a second direction that is not orthogonal to the said first direction; and a tunnel barrier layer between the free and reference layers.
