Beacon Transcript – Terahertz Rays (T-Rays) may mark an increase in our computer memory speed as scientists have proven the rays’ applicability in the computer domain.
A team from the Moscow Institute of Physics and Technology scientists in collaboration with their German and Netherlands partners released a paper that could boost the evolution of the computer world.
The paper, released in the Nature Photonics journal, revealed the team’s plan of using terahertz rays in order to speed up a computer’s memory. The effect could be achieved through the use of T-rays so as to reset computer memory cells.
Terahertz radiation, or T-waves, have been proven by the researchers to offer an end result that is faster by several thousand times as compared to the current magnetic-field-induced switch processes.
Their magnetization process, which is a never before tried idea, features the use of short electromagnetic pulses set at terahertz frequencies that then trigger magnetic subsystem oscillations. The proven efficiency of this mechanism could mark an important step towards the future use of terahertz electronics.
As technology is evolving at a faster than ever before rate and more and more digital data has to be both stored and manipulated, scientists are searching for new techniques that will sustain the continual growth.
One the factors holding back current computer technologies comes in the form of the memory. A magnetic memory cell requires quite a lengthy time span in order to complete its set and reset operations, and reducing the time frame is one of the scientists’ biggest challenges.
As current, classical computation is thought to be slowly but surely reaching its limit, with no possible foreseeable further advance in data processing speed, this new mechanism could signify the breakthrough researchers everywhere have been waiting for.
This could be the future basis of more complex computation tasks and the impulse needed by hardware designers in order to come up with a higher computational speed.
The Russian-German-Dutch collaboration tested their terahertz rays idea in relation with thulium orthoferrite. This is a weak ferromagnet that generates magnetic fields due to the ordered alignment of its magnetic moments. Its atoms’ spins can be reoriented only with the help of a magnetic field external to its own.
Their tests have shown, in contrast, that by using terahertz radiation it is possible to directly control the magnetization. It also demonstrated a faster and more efficient technique for remagnetization, as it was 10 times faster than that obtained through the use of an external magnetic field.
Scientists are confident that the “T-ray switching” will work just as well on other magnetic materials, and point out a past Soviet research that conducted a similar study, but used a different material.
Terahertz rays are more commonly used nowadays in medical imaging, full body scans and a variety of other manufacturing and communications processes.
