Researchers develop a spintronics memory that switches its magnetization in 6 picoseconds

An international group of researchers, led by the CNRS, developed a new technique that can switch magnetization in only six picoseconds, which is almost 100-times faster than current state-of-the-art spintronics. The new technique is also highly efficient.

The experimental design used to create the ultra-fast magnetization switching included an optical pump directed at the photoconductive switch, which converts the light into 6-picosecond electric pulses. The structure guides these pulses toward the magnet. When the pulses reach the magnet, they trigger the magnetization switching.
