Figure 6.6 Bennett clocking of a multiferroic logic wire to propagate a

bit unidirectionally down the chain. First row shows an array in ground

state with antiferromagnetic ordering of the magnetizations representing

a sequence of bits [0101...]. In the second row, the first bit is flipped

and the second magnet now finds itself in a frustrated state since its

left neighbor tells it to flip and the right neighbor tells it to stay put. In

order to resolve the tie and make the second magnet flip up (so that we

ultimately end up with the desired sequence [1010] where the ...
