The two answers given so far are wrong. A magnon is an excitation carrying spin-$1$. A spinon is an excitation carryong spin-$\frac {1} {2}$. This has nothing to do with it being an excitation above a ferro- or antiferromagnet. The difference is much more dramatic, such that magnons are 'normal'/standard, yet spinons are very special.It exploits magnon properties instead of current, with vibrations being used to change the value of the input going to the logic gate as interference between waves occurs. Based on the amplitude and phase of the interacting waves, the logic gate spits out one of its binary values in a predetermined wave.Cro-Magnon 1 is a middle-aged, male skeleton of one of the four adults found in the cave at Cro-Magnon.
