Advance in US laboratory uses ultrathin materials and spin control to create more efficient and compact spintronic devices.

Scientists at the Argonne National Laboratory, affiliated with the United States Department of Energy, have achieved a significant milestone in the development of electronics and cutting-edge computing.

Through the study of atomically thin magnetic materials, the team was able to map the behavior of internal magnetic domains, providing a pathway for faster and more efficient devices. The research focuses on the precise control of magnetic states and electron spins at extremely reduced scales.

The potential of Van der Waals magnets

The researchers used so-called Van der Waals magnets, ultrathin materials that can be separated into layers just a few atoms thick. These materials are considered fundamental building blocks for spintronic devices, a technology that uses the electron’s spin, in addition to its charge, to process data.

Control of skyrmions and magnetic density

The investigation at Argonne allowed the discovery of how the thickness of the material and the intensity of the applied magnetic fields influence the size and evolution of skyrmions. Skyrmions are stable and tiny magnetic structures that can act as information carriers in high-density data storage systems. The ability to predict the resulting domain patterns under different cooling conditions represents an advancement for precision engineering in nanotechnology.

The work provides a roadmap for engineers to reliably adjust the size and density of these structures. Mastering magnetism in atomically thin materials is a crucial step toward making spin-based computing a commercial reality. If it is possible to manipulate these elements precisely, the industry could build technologies that were previously confined to the realm of scientific imagination.

Toward energy efficiency in computing

The transition to devices based on cutting-edge electronics and computing promises to drastically reduce the energy consumption of current systems. Unlike traditional electronics, which move electric charges and generate heat through resistance, spintronics operates with the orientation of spins, minimizing energy losses.

The research demonstrates that the behavior of magnetic domains can be predicted and controlled according to the needs of each application.

With these results, the Argonne National Laboratory establishes a solid foundation for the creation of denser magnetic memories and faster processors. The integration of these new materials could revolutionize the way data is processed and stored globally. The success in mapping at the atomic scale brings society closer to a smarter and more sustainable technological infrastructure.

While a traditional school may take several days just to raise walls, in Malawi a 3D-printed school had its structure ready in 18 hours, welcomed children in June, and showed a new solution to the lack of classrooms.

Material once seen as a poor man’s choice returns as a climate bet, with red clay replacing part of the gray concrete in modern buildings, hospitals, houses, and a cultural center that transforms tradition into a solution against urban heat.

Australia prepares to dredge 96.5 million m³ in Moreton Bay to deepen, widen, and realign channels of the Port of Brisbane, in a project of up to 25 years designed to accommodate larger ships and enhance maritime safety and regional port efficiency.

Study solves great ancient mystery: remains of Philip II, father of Alexander the Great, are identified in Vergina and resolves the enigma of the Macedonian royal tombs that had lasted half a century.

Larger than the Toyota Hilux and with a towing capacity of 3.5 tons, the new MG U9 2026 features a 2.5 turbodiesel engine, 520 Nm, 4×4 traction with three locks, and an almost full-size build.

Portugal installs two giant underwater sockets to draw water from the Atlantic and create a €107.9 million desalination plant in the Algarve capable of producing 43.2 million liters of potable water per day with ocean intake 2 km from the coast.

Forget salt on the roads: researchers test asphalt with passive geothermal energy in Spain, capable of heating the road from below, reducing black ice, and using IoT sensors without relying on pumps, external electricity, or chemicals in the European winter.

How does Brazil manage to deliver 13 gas cylinders per second?

R$ 27.6 billion will be invested in the largest railway in Brazil under an agreement that renews the VLI concession in Centro-Atlântica for another 30 years and returns to the Union about 3,100 km of tracks considered deficient, which may go to new operators.

Research with DNA extracted from feces showed that the elephants known as “ghosts” in the highlands of eastern Angola form a distinct genetic lineage, with closer proximity to populations from Namibia.

A robot named Walter does the work of five bricklayers per hour and can save the construction industry, where the average age of professionals is 46 years and almost no one wants to learn the trade anymore, in the United Kingdom.
