As an added bonus, the magnetic ordering temperature can be tuned by changing the ratio or germanium to silicon.

To get the two pendulums to communicate, the physicists fed data about the real pendulum to the virtual one, and transferred information from the virtual ...American Chemical Society's Weekly PressPac -- May 30, 2007
