A group of researchers from the Eindhoven University of Technology has just unveiled a new ultra-fast data storage technology that promises to revolutionize the future of hard drives. More capacity, faster, more durability, the new storage systems could become a reality in just a few years.

The team of physicists, led by Professor Bert Koopmans, used a special property of electrons, the spin (which is a kind of internal compass or intrinsic rotation of the electron). Using ultra-fast laser pulses, the researchers generated a flow of electrons inside a material that had the peculiarity of having the same spin. Which led to a kind of “spin current” that was capable of changing the magnetic properties of the material in which it was found.

“This change in magnetization,” explains Schellekens, “occurs in just about 100 femtoseconds (a femtosecond is one billionth of a second), that is, a thousand times faster than current technology allows.”
