摘要： PROBLEM TO BE SOLVED: To provide writing wiring effective for a CPP type giant magnetoresistance device, more particularly a solid-state magnetic memory, to uniformly write respective magnetic materials with a small current quantity and to improve the selectivity of cells. SOLUTION: Magnetic layers and nonmagnetic layers are laminated in portions or the whole in pores of the magnetic device which has pore layers on a substrate and has wiring above and below the pore layers. Portions of the pores are formed as the writing lines to the adjacent laminated magnetic materials. Particularly a higher effect may be obtained by using anodically oxidized alumina layers as the pore layers and providing the device with the shielding pores to enhance the sell selectivity. A Co/Cu component is effective for the laminated magnetic materials and Cu is effective for the writing wiring. The pores are preferably honeycomb arrangement and rectangular arrangement.

By accelerating electons emitted by the electron source 2 and then casting them on the laser structure 3, the laser structure 3 is allowed to generate laser light. The light reflection sections 5, 6 of the laser structure 3 have a multidimensional photonic crystal structure wherein dielectric materials having different permittivities are periodically arranged in multidimensional directions. Both the light emission section 4 and the light reflection sections 5, 6 have the multidimensional photonic crystal structure.
