摘要： An electromagnetic field detecting element 10 includes a lamination of three insulation layers 2, 3, and 4. The dielectric breakdown strength of the insulation layer 3 is greater than the dielectric breakdown strengths of insulation layers 2 and 4. The three insulation layers 2, 3, and 4 are disposed between a pair of electrodes 5 and 6. Boundaries 7 and 8 on both ends of an overlapping region of the opposing surfaces 5a and 6a in a Z direction are apart from the insulation layer 3 by thicknesses t1 and t3 of the insulation layers 2 and 4, respectively. Between the pair of electrodes 5 and 6, ballistic current paths interposing therebetween the insulation layer 3 are formed by applying, between the pair of electrodes 5 and 6, an electric field having a magnitude which causes dielectric breakdown in the insulation layers 2 and 4 while causing no dielectric breakdown in the insulation layer 3. Thus, it is possible to perform at a room temperature a highly efficient electromagnetic field detection utilizing AB effect or AC effect.

摘要： A magnetic sensing section is constituted by a magneto-resistive device in which a fixed magnetization layer, a non-magnetic layer, and a magnetization-free layer are deposited in that order on a first buffer layer that is deposited on a magnetic layer. A second buffer layer sandwiches the magnetic sensing section, and a biasing layer which covers right and left sides of the magnetic sensing section. The second buffer layer is deposited on the magnetic layer with a nonconductor layer interposed therebetween. A near field light generation section constituted by a second magnetic layer, a dielectric layer, and a metal layer is formed on a surface of the second buffer layer not adjacent to the nonconductor layer. The resultant magnetic sensor device can efficiently perform photo-assisted reproduction of information from a magnetic recording medium using a magnetic reproduction head or a magnetic reproducer.
