    Abstract: A magneto-resistance effect head is provided with a lower conductive layer which is provided with a recessed portion, and a vertical bias layer is provided in the recessed portion. A first magnetic layer is provided on the lower conductive layer. On the first magnetic layer, layered in the following order are the non-magnetic layer, the fixed layer, the fixing layer, and the upper layer so as not to be placed immediately above the vertical bias layer. The non-magnetic layer, the fixed layer, the fixing layer, and the upper layer are buried in an insulation layer. Furthermore, an upper conductive layer is provided on the upper layer and the insulation layer. In the direction of the magnetic field applied by the vertical bias layer, the free layer is made greater in length than the fixed layer and the free layer is disposed in proximity to the vertical bias layer with the distance between the fixed layer and the vertical bias layer remaining unchanged.

  • Publication number: 20070253051
    Abstract: A conductive thin film has first and second surfaces and at least one opening extending through from the first surface to the second surface. At least on one of the first and second surfaces, first and second periodic surface patterns having different period lengths are provided. The period length of the second periodic surface pattern is substantially equal to an odd integral multiple of a half of the period length of the first periodic surface pattern. With this, surface plasmon polaritons excited by the first periodic surface pattern undergo odd-order Bragg reflection by the second periodic surface pattern. As a result, the intensity of the light falling on the first surface and transmitted to the second surface through the opening is increased with high efficiency.

  • Patent number: 7265949
    Abstract: A magneto-resistance effect element is adapted that a non-magnetic layer (9, 18), a free layer (3b, 19), another non-magnetic layer (4, 25), a fixed layer (5, 26), and a fixing layer (6b, 27) are formed vertically symmetric with respect to a first magnetic layer (8b), to which a vertical bias magnetic field is applied from an underlying layer (2a) for a vertical bias layer (2b). The magneto-resistance effect element operates in CPP mode. Generally, the free layer is unavoidably subjected to the influence of a circular electric magnetic field caused by a current flowing perpendicularly to the film surface. However, in the magneto-resistance effect element, the influence of the electric magnetic field to which the free layer (3b) is subjected is opposite to that of the electric magnetic field to which the second free layer (19) is subjected, thereby canceling out the influences as a hole.
