Problems solved by technology

In the case of the CPP type magnetic detection element, there is no need to remove the above-mentioned metal mask layer 7, but in the case of the CPP type magnetic detection element, the free magnetic layer 5 under the above-mentioned metal mask layer 7 is not changed, so that it is different from the CIP type magnetic detection element together cannot properly form a magnetic detection element with good regenerative characteristics

Embodiment Construction

[0049] figure 1 It is a partial cross-sectional view showing the structure of the tunnel-type magnetic detection element according to the present embodiment, cut in a direction parallel to the facing surface of the recording medium.

[0050] The tunnel-type magnetic detection element is installed on the driven-side end of a floating slider provided on the hard disk device, etc., and detects a recording magnetic field of the hard disk or the like. In the figure, the X direction is the track width direction, the Y direction is the direction (height direction) of the leakage magnetic field from the magnetic recording medium, and the Z direction is the moving direction of the magnetic recording medium such as a hard disk and the above-mentioned tunnel type magnetic detection element. As for the stacking direction of the layers, the X-Z plane is a plane parallel to the opposing surface of the recording medium.

[0051] Reference numeral 20 denotes a lower shield layer, and the lo...

Abstract

There is provided a magnetic detecting element and a method of manufacturing the same. An intermediate layer and a corrosion preventing layer are laminated on a free magnetic layer. The corrosion preventing layer prevents the free magnetic layer from corroding due to reactive ion etching. Therefore, a laminator can be correspondingly formed in a predetermined shape, and the free magnetic layer can be prevented from corroding. As a result, it is possible to manufacture a magnetic detecting element having excellent reproduction output.

Description

technical field [0001] In particular, the present invention relates to a magnetic detection element and a method for manufacturing the same, which can be used to form a laminate having a fixed magnetic layer, a non-magnetic material layer, and a free magnetic layer into a predetermined shape using a mask layer for forming the laminate. The body is properly formed into a predetermined shape, and corrosion of the above-mentioned free magnetic layer can be prevented. Background technique [0002] The following Patent Documents 1 and 2 disclose the structure of a CIP (Current In Plane) type magnetic detection element. The so-called CIP type refers to the film in which the current is connected to each layer of the laminated body (the laminated part having a four-layer structure of an antiferromagnetic layer, a fixed magnetic layer, a nonmagnetic material layer, and a free magnetic layer) that constitutes the above-mentioned magnetic detection element. A structure that flows in a...
