Physicists manipulate material properties with light pulses
Researchers at the University of Konstanz have developed a technique to alter the magnetic properties of materials using laser pulses, effectively transforming one material into another at room temperature. By exciting pairs of magnons in common haematite crystals, the method enables non-thermal control of magnetic states and potential data transmission at terahertz speeds. This breakthrough could allow quantum effects to be studied without extreme cooling.
