摘要： A FePt alloy nanoparticle, which is expected to be a promising material used for an ultra-high-density magnetic recording medium of the next generation, is ordered by heat treatment to have high magnetic anisotropy, but there has been a problem that the particles are coalesced with each other and agglomerate during the heat treatment. According to the present invention, each particle of the alloy nanoparticles is covered with a coating such as SiO2, and thereafter a heat treatment for ordering is carried out. In this method, the alloy nanoparticles do not coalesce with each other even if the heat treatment is performed at such a high temperature as to allow all the particles to be fully ordered. After the heat treatment, only the coating is removed using an acid or alkali solution so that it is possible to obtain ordered alloy phase nanoparticles which are ordered and dispersible in various solutions. It is also possible to easily manufacture an ultra-high-density magnetic recording medium by coating surfaces of a substrate with a binder solution in which the particles are dispersed while applying a magnetic field in a predetermined direction.

摘要： The present invention uses a ferromagnetic thin wire having a domain wall inside, with the magnetic moment at the center thereof being perpendicular to the longitudinal axis of the thin wire. With the domain wall being fixed by a domain wall fixation device (e.g. antiferromagnetic thin wires) so that the domain wall is prevented from moving in the ferromagnetic thin wire, when a direct current is supplied, the magnetic moment rotates in the immobilized domain wall. This rotation of the moment can be detected by a TMR element or the like. This configuration of the ferromagnetic thin wire element can be directly used to create a microwave oscillator or magnetic memory.

摘要： In one embodiment of the present invention, an MRAM is an MRAM including: a plurality of write word lines; a plurality of bit lines provided so as to intersect with the write word lines; and TMR elements provided at respective intersections of the write word lines and the bit lines. Each of the TMR elements includes a first ferromagnetic layer of which magnetization direction is variable, a second ferromagnetic layer of which magnetization direction is fixed, and a tunnel wall which is sandwiched between the first ferromagnetic layer and the second ferromagnetic layer. The bit line is provided, for example, so as to bulge in the direction in which the write word line extends at the intersection of the bit line and the write word line, so that a magnetic wall is introduced at a desired position of the bit line. Further, a current fed through the bit line is fed through the first ferromagnetic layer at the time of data writing. This makes it possible to provide the MRAM having a gigabit-class capacity.

摘要： The present invention provides a novel element capable of simply controlling an in-plane rotational motion of a core (a rising spot of a magnetization) generated in the center of a ferromagnetic dot made by forming a ferromagnetic material into a nanosized disk shape. In addition, the present invention is achieved to provide a binary information memory element using a core, including a ferromagnetic dot, made of a disk-shaped ferromagnetic material, with a magnetic structure of a magnetic vortex structure, and a current supplier for supplying an alternating current with a predetermined alternating current in the radial direction of the ferromagnetic dot. In the case where the frequency of the current resonates with the intrinsic frequency of the ferromagnetic dot, it is possible to rotate the core in the plane of the dot. Since the core leaks a magnetic field, a microscopic actuator such as a motor can be obtained by using this element. Furthermore, supplying a current having a density not less than a predetermined value reverses the core. This allows the expression of binary information.

摘要： A multilayered circuit board for a semiconductor chip module includes an underlying board, insulating layers, fixed-potential wiring layers, via holes, and metal layers. The underlying board has a major surface made of a metal material to which a fixed potential is applied. The insulating layers are stacked on the major surface of the underlying board and have wiring layers formed on their surfaces. The fixed-potential wiring layers constitute part of the wiring layers formed on the insulating layers. The via holes are formed below the fixed-potential wiring layers to extend through the insulating layers. The metal layers are filled in the via holes so as to make upper ends be connected to the lower surfaces of the fixed-potential wiring layers. One of the insulating layers in contact with the major surface of the underlying board is formed on the underlying board while the lower end of the metal layer is in contact with the major surface of the underlying board. The other insulating layer formed on the insulating layer in contact with the major surface of the underlying board is stacked while the lower end of the metal layer is in contact with the upper surface of the fixed-potential wiring layer of one insulating layer.
