Antiferromagnetic materials allow for processing at terahertz speeds

In high-speed fiber optics, it is often the case that either the bandwidth of the transmission media cannot keep up with the data flow or the data simply cannot be processed fast enough. Then the picture judders or the resolution is temporarily scaled down, and television viewers have to make do with lower resolution images. Soon, such low bandwidth could be a thing of the past. Researchers at the Czech Academy of Sciences, together with their colleagues at Mainz University, have discovered a wa...
