| Popis: | In this paper, we have characterized the magnetic field from waveguides with widths ranging from 1 /spl mu/m to < 100 nm, in both single and dual wire geometrics. Our Cu waveguides are fabricated by a combination of conventional optical lithography and electron beam lithography. The magnetic field of the wire is detected using giant magnetoresistance (GMR) read sensors, and the measurements are performed. |
