UTEP researchers enhance magnets for computing
EL PASO, Texas (November 20, 2023) – With demand for elevated knowledge storage and faster-performance computer systems, researchers are creating a brand new era of supplies to fulfill client expectations.
A staff led by physicist Srinivasa Singamaneni (entrance) has found a brand new kind of magnet that could possibly be utilized in quantum computing. Magnets function at temperatures as much as 170 levels Fahrenheit.
“How can we design new supplies to allow them to retailer knowledge at a smaller quantity, at a decrease value, and utilizing much less vitality?” requested Srinivasa Singamaneni, Ph.D., affiliate professor within the Division of Physics on the College of Texas at El Paso
The reply could lie in a brand new kind of magnet found by Singamaneni and UTEP physicists. The fabric is described within the Nature journal npj 2D Supplies and Functions.
“Many researchers are exploring quantum magnets to revolutionize the way forward for computational energy,” Singamaneni mentioned. “Quite a lot of devices use conventional magnets — laptops, audio system, headphones, MRI scanners — and these magnets could possibly be changed by quantum magnets someday.”
Singamaneni, lead creator of the brand new examine, has been engaged on a category of magnets referred to as van der Waals magnets since 2021. The brand new 2D magnets — which have a size and width however are just one layer thick — have enormous potential on the planet of computing due to their small measurement, Singamaneni mentioned.
Nonetheless, van der Waals magnets have solely labored at temperatures under freezing, till now.
In collaboration with a staff of scientists from Stanford College, the College of Edinburgh, Los Alamos Nationwide Laboratory, the Nationwide Institute of Requirements and Know-how (NIST) and Brookhaven Nationwide Laboratory, Singamaneni found that including a low-cost natural materials – referred to as tetrabutylammonium – between the atomic layers of a magnet permits the magnets to work At temperatures as much as 170 levels Fahrenheit.
“Van der Waals magnets don’t have any sensible functions in the intervening time as a consequence of their temperature limitations,” Singamaneni mentioned. “My method is exclusive as a result of we’ve proven that straightforward chemical manipulation of a definite magnet can transcend the bounds of 2D magnetism; this could possibly be utterly transformative for the trade.”
The staff has demonstrated the potential of magnets on the laboratory degree, however plans to proceed learning the fabric and bettering it to be used in computing.
Extra authors on the examine are UTEP alumnus Hector Iturriaga, at the moment at Stanford College; UTEP graduate scholar Luis M. Martinez and UTEP students Sriprasad Srinivasan, Ph.D., and Muhammad Sanad, Ph.D.; NIST scientists Thuc Could, Ph.D., Adam Biachey, Ph.D., and Angela Hite-Walker, Ph.D.; College of Edinburgh scientists Matthias Augustin, Ph.D., and Elton Santos, Ph.D.; Yu Liu, PhD, Los Alamos Nationwide Laboratory; And Cedomir Petrovic, Ph.D., of Brookhaven Nationwide Laboratory.
Concerning the College of Texas at El Paso
The College of Texas at El Paso is America’s main Hispanic-serving college. Positioned on the westernmost tip of Texas, the place three states and two nations meet alongside the Rio Grande River, 84% of our 24,000 college students are Hispanic, and greater than half are the primary of their households to attend school. UTEP gives 171 bachelor’s, grasp’s, and doctoral diploma applications at America’s solely premier open-access analysis college.
