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.
