Submicrometer ferromagnetic NOT gate and shift register.

Allwood, D. A. and Xiong, G. and Cooke, M. D. and Faulkner, C. C. and Atkinson, D. and Vernier, N. and Cowburn, R. P. (2002) 'Submicrometer ferromagnetic NOT gate and shift register.', Science., 296 (5575). pp. 2003-2006.


An all-metallic submicrometer device is demonstrated experimentally at room temperature that performs logical NOT operations on magnetic logic signals. When this two-terminal ferromagnetic structure is incorporated into a magnetic feedback loop, the junction performs a frequency division operation on an applied oscillating magnetic field. Up to 11 of these junctions are then directly linked together to create a magnetic shift register.
