Photonics of spin: Femtosecond lasers for Reading/Writing Hard Drives 100,000 Times Faster
Femtosecond lasers have been demonstrated for use in reading/writing hard drives 100,000 times faster. 50-femtosecond read and write times for spintronics could be possible. Abstract Nature Physics: Coherent ultrafast magnetism induced by femtosecond laser pulses The quest for ultrafast magnetic processes has triggered a new field of research—femtomagnetism: using femtosecond laser pulses to demagnetize ferromagnetic …
