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.

18. The magnetization transitions shown in Fig. 2C indicate
that domain walls require a parallel magnetic
Þeld of just 3 Oe to propagate in continuous wire
sections, which is when the orthogonal component of
the rotating Þeld is close to its maximum value.

21. In the previous case of one NOT gate in a feedback
loop, no pulsed-Þeld initialization was required owing
to the simpler topology involved.
