Terahertz light used to create non-volatile data storage in new study
Terahertz light can reversibly switch an unusual form of structural order in solids, called ferroaxiality, between clockwise and anti-clockwise rotational patterns (Image: Jörg Harms / Max Planck Institute for the Structure and Dynamics of Matter)
Scientists from the Max Planck Institute say they have successfully used circular terahertz light to switch ferroaxial domains, opening up ultrafast memory
