Researchers from the Institute of Physics of the Czech Academy of Sciences and Charles University have reported on their new experiment in which they succeeded to write information into an antiferromagnet by femtosecond-laser pulses. A Femtosecond and a second are separated by fifteen orders of magnitude which is about the same as the number of orders between a second and the age of the universe. Moreover, their antiferromagnets behave like elements forming a human brain – neurons – rather than conventional digital devices.
