摘要： A magnetic head having a laminated magnetic film in which crystal orientation of precipitated small crystal particles can be controlled and the soft magnetic characteristic in the thickness of the laminated magnetic film can easily be controlled. The magnetic head has the laminated magnetic film formed by laminating thin magnetic layers, each having a composition as Fe.sub.x M.sub.y N.sub.z, and metal layers. The laminated magnetic film is subjected to heat treatment so that metal atoms forming the metal layers are diffused into the thin magnetic films. Thus, the laminated magnetic film contains small crystal particles of .alpha.Fe, the direction of crystal of which is controlled by the diffused metal atoms. Therefore, the laminated magnetic film has an excellent soft magnetic characteristic also in the direction of the thickness thereof.

摘要： A spiral spring arrangement consists essentially of two spiral springs. The spring arrangement comprises an immovable member, a rotatable shaft, and a rotatively movable member. One of the spiral springs has one end connected to the immovable member and the other end to the rotatable shaft. The other spiral spring has one end connected to the rotatable shaft and the other end to the rotatively movable member. The rotatably movable member serves as the point acting on the spiral springs. The two spiral springs are in a serial relationship, thus reducing the spring constant against rotation.

摘要： First and second magnetic layers are laminated though a tunnel barrier layer, wherein a region is formed in which change in a magnetic resistance ratio with respect to change in a voltage applied in such a manner that the second magnetic layer has a lower potential as compared with the potential of the first magnetic layer is smaller than change in a magnetic resistance ratio with respect to change in a voltage applied in such a manner that the second magnetic layer has a higher potential as compared with the potential of the first magnetic layer. Voltage is applied to the magnetic tunnel device in such a manner that the potential of the second magnetic layer is lower than that of the first magnetic layer so that dependency of the magnetic resistance ratio on the voltage is reduced. Thus, a stable tunnel current flows.

摘要： A magnetic head comprising a pair of magnetic core halves each having a magnetic core film sandwiched between a pair of non-magnetic substrates, said magnetic core halves being abutted to each other with the end faces of the magnetic core films facing each other, with a magnetic gap being defined in an interface of abutment of said magnetic core films, wherein the magnetic core film is of a laminated magnetic film structure comprising a plurality of laminated magnetic film units laminated with insulating films in-between. Each laminated magnetic film unit in turn comprises a plurality of magnetic films with non-magnetic films in-between, with the magnetic films being magnetostatically connected to one another at film ends. By employing the laminated magnetic film unit for the magnetic core film, it becomes possible to markedly increase the magnetic permeability in a direction normal to the gap depth when anisotropy is applied in the gap depth direction. With the above magnetic head, a plurality of the magnetic film units are laminated with insulating films in-between for suppressing eddy current losses in the high frequency region. As a result, excellent electro-magnetic transducing characteristics may be obtained in the high frequency range.
