#NewsPaper -- Oct. 16, 2020 Researchers at the Université de Lorraine in France and Tohoku University reported on an innovative technology that leads to a drastic reduction in energy for data storage. The established technology utilizes an ultrafast laser pulse whose duration is as short as 30 femto seconds—equal to 0.0000000000000003 seconds. The laser pulse is applied to a heterostructure consisting of ferrimagnetic GdFeCo, nonmagnetic Cu and ferromagnetic Co/Pt layers.
