摘要： There is provided a magnetoresistance effect element which is capable of causing a large sense current to flow between electrodes and which has a smaller dispersion in direction of magnetization of a CPP element based on a magnetic field due to the sense current and has a lager reproducing output, and a method for producing the same. The magnetoresistance effect element is produced by: after forming a first electrode, forming a magnetoresistance effect film on the first electrode; applying a self-condensing organic resist on the magnetoresistance effect film, and thereafter, causing the organic resist to be droplets; subsequently, forming an insulating film thereon, and thereafter, removing the organic resist to form a groove portion in the insulating film to expose the top surface of the magnetoresistance effect film; and filling the groove portion with an electrode material to form a second electrode.

摘要： A magnetic memory element is provided with first and second ferromagnetic fixed layers, a ferromagnetic memory layer, nonmagnetic first and second intermediate layers. The memory layer is disposed between the first and second fixed layers, and has a variable magnetization direction. In order to cancel asymmetry of a write-in current of the element, the element is provided so that the memory layer receives a larger perpendicular stray field from the first fixed layer than from the second fixed layer, and then a magnetization direction of a portion of the memory layer being nearest to the first intermediate layer and the magnetization direction of the first fixed layer are antiparallel to each other whenever a magnetization direction of a portion of the memory layer being nearest to the second intermediate layer and the magnetization direction of the second fixed layer are parallel to each other, and vice versa.

摘要： It is possible to obtain sensitivity which can achieve an excellent error rate with a high recording density. There are provided a magnetization free layer which has two opposed main surfaces, one of which is set to be generally parallel to an air bearing surface; an intermediate layer which is formed on an opposite side face of the magnetization free layer from a medium to come in contact with the magnetization free layer; and a pair of magnetization pinned layers which are formed on an opposite side face of the intermediate layer from the magnetization free layer to come in contact with the intermediate layer and extend outwardly. A sense current flows from one magnetization pinned layer to the other magnetization pinned layer through the magnetization free layer.
