The demands for data storage and processing have grown exponentially as the world turns into increasingly connected, emphasizing the need for new supplies capable of more efficient data storage and data processing.
An international crew of researchers, guided by physicist Paul Ching-Wu Chu, founding director of the Texas Center for Superconductivity at the University of Houston, is reporting a brand new compound capable of sustaining its skyrmion properties at room temperature by using excessive pressure. The outcomes additionally recommend the potential for using chemical pressure to maintain the properties at ambient stress, providing promise for commercial applications.
A skyrmion is the smallest perturbation to a uniform magnet, a point-like area of reversed magnetization surrounded by a whirling twist of spins.
These tiny areas, together with the possibility of moving them utilizing tiny electrical current, make the supplies hosting them promising candidates for high-density info storage. However, the skyrmion state usually exists only at a meager and narrow temperature range.
For instance, in the compound Chu and colleagues studied, the skyrmion state exists inside a narrow temperature range of about three Kelvin degrees, between 55 K and 58.5 K. That makes it impractical for many applications.
