We’re all used to the changes in the properties of radio frequency systems as the frequency ... but infrared light. Terahertz waves are the electromagnetic radiation that lies in that area ...

The frequency around 1 THz between radio waves and light is called the terahertz band (or submillimeter waveband, far infrared), and has yet to be developed. Light sources and detectors that generate ...

By applying intense pulses of terahertz-frequency light to this material, they were able to control this transition, placing the material in a metastable magnetic state that lasts for more than 2.5 ...
