Magnet structure and operation
The single molecule magnet (SMM) is formed by a disciprosium atom attached between two nitrogen atoms and stabilized by a chemical group called alkene. This structure allowed the material to function reliably up to 100 Kelvin (about –173 ° C), surpassing the previous record of 80 K.
This advance represents an important milestone because it brings practical applications closer, such as use on data centers. The magnet remains functional at liquid nitrogen temperatures, which is accessible and widely used in industrial environments.
Capacity comparable to 1 petabyte
According to the researchers, the new material has the potential to reach densities of up to 3 terabytes per square centimeter. For comparison, this would be enough to store about 500,000 short Tiktok videos in an area the size of a postal seal.
The data density achieved with this new magnet exceeds 100 times that of the most advanced rigid discs available today on the market. To get an idea, a single 3.5 inch disc could reach up to 1 petabyte capacity, a number comparable to projects like SSD E2 with 1 PB storage.
Thermal stability is essential
Scientists point out that magnetic stability at higher temperatures is essential for technology to get out of the laboratories and reach the market. The innovative molecular structure allowed the magnetic spin of the disciprosium to remain isolated even under challenging conditions.
Recognition of the scientific community
The discovery was published in the prestigious magazine Nature and repercussions in several international vehicles, such as Tom’s Hardware, Phys.org, New Atlas e Interesting Engineering. The subjects highlight the potential use of technology on advanced computing devices and massive data storage.
This new type of magnet represents a revolution compared to current technologies, which are already evolving with solutions such as 976 TB highpoint in external storage or even record data transmissions, such as the recent sending of 1 PB/s per fiber optics.
Potential beyond HDs
In addition to the direct impact on HDs, research paves the way for applications in various areas of technology. Because they are formed by individual atomic structures, these magnets allow precise control of bits on a molecular scale. See some possible applications:
- Quantum computing: The magnetic control on atomic scale can be used to represent quibits with higher thermal stability.
- Ultrasound sensors: SMMS can be used to detect minimum magnetic field variations, with application on medical and scientific equipment.
- Ultra High Density Storage: Extreme miniaturization opens doors for storage solutions on mobile devices, servers and even satellites.
- Advanced electronic components: Molecular magnets can be integrated into future chips with controlled magnetism by temperature and electric current.
The combination of thermal stability, high density and small size makes this new magnet a promising alternative to current technologies, such as heat assisted magnetic records (HAMR) or Ultra Resolution solutions provided for 16K HDMI 2.2.
FUTURE CHALLENGES
Despite the enthusiasm, scientists still need to overcome challenges, such as production scaling and the integration of SMMs with conventional electronic systems. Still, the advance represents a significant step towards data storage at the atomic level.
