20090080123 | MAGNETORESISTANCE EFFECT ELEMENT AND MAGNETORESISTIVE DEVICE - The high quality magnetoresistance effect element is capable of reducing resistance in the perpendicular-plane direction and preventing performance deterioration of a barrier layer. The magnetoresistance effect element comprises: a free layer; a pinned magnetic layer; and a barrier layer being provided between the free layer and the pinned magnetic layer, and the barrier layer is composed of a semiconductor. | 03-26-2009 |
20090168270 | EXCHANGE-COUPLED ELEMENT AND MAGNETORESISTANCE EFFECT ELEMENT - In comparison with conventional exchange-coupled elements, the exchange-coupled element of the present invention has greater unidirectional magnetization anisotropy. The exchange-coupled element comprises: an ordered antiferromagnetic layer; and a pinned magnetic layer being exchange-coupled with the ordered antiferromagnetic layer, the pinned magnetic layer having unidirectional magnetization anisotropy. The pinned magnetic layer is constituted by a first pinned magnetic layer having a composition, which can have a face-centered cubic lattice structure, and a second pinned magnetic layer having a composition, which can have a body-centered cubic lattice structure. | 07-02-2009 |
20090169915 | METHOD OF PRODUCING MAGNETORESISTANCE EFFECT ELEMENT AND MAGNETORESISTANCE EFFECT ELEMENT - The method of the present invention provides a magnetoresistance effect element, which is capable of having a high MR ratio, corresponding to high density recording and being suitably applied to a magnetoresistance device even though a barrier layer is thinned to reduce resistance of the magnetoresistance effect element. The method of producing the magnetoresistance effect element, which includes the barrier layer composed of an oxidized metal, a first magnetic layer contacting one of surfaces of the barrier layer and a second magnetic layer contacting the other surface thereof, comprises the steps of: laminating the barrier layer on the first magnetic layer with using a target composed of the oxidized metal; and laminating the second magnetic layer on the barrier layer. The barrier layer is annealed before laminating the second magnetic layer thereon. | 07-02-2009 |
