Scientists at the US Department of Energy's Ames Laboratory have discovered the relaxation dynamics of a zero-field state in skyrmions, a spinning magnetic phenomenon that has potential applications in data storage and spintronic devices.
Scientists of the Far Eastern Federal University, together with Russian and foreign colleagues, developed samples of nickel mesoporous film structures, which have useful surface area up to 400 times greater than their solid one. Brand new material can be used in energy saving, chemical industry and other practical areas. The research results are published in Applied Surface Science journal.
Using a new computational method, an international collaboration has succeeded for the first time in systematically investigating magnetic quantum effects in the well-known 3D pyrochlore Heisenberg model. The surprising finding: physical quantum phases are formed only for small spin values.
Researchers from Osaka University, in collaboration with the National Institute of Advanced Industrial Science and Technology (AIST) and Grenoble Alpes University, succeeded in efficiently controlling the direction of a nano-sized magnet by heating at high speed. The researchers also discovered that nano-magnets amplify microwave signals. These achievements will contribute to reducing power consumption for magnetoresistive random access memory and artificial intelligence devices, helping us move towards a super-smart society.
Now, researchers at the University of Missouri have discovered spin flips happen in one half of one trillionth of a second, or half a picosecond in the course of a chemical reaction. To understand how fast it is -- watches count in seconds, sporting games are timed in 10ths of a second, and light travels just under 12 inches in one-billionth of a second. Spin flips are faster.
Researchers of the Eindhoven University of Technology (TU/e) have developed a 'hybrid technology' which shows the advantages of both light and magnetic hard drives. Ultra-short (femtosecond) light pulses allows data to be directly written in a magnetic memory in a fast and highly energy-efficient way. This research, published in Nature Communications, promises to revolutionize the process of data storage in future photonic integrated circuits.
In a paper published today in Nature Communications, Vardeny, along with Jingying Wang, Dali Sun (now at North Carolina State University) and colleagues present two devices built using perovskite to demonstrate the material's potential in spintronic systems. Its properties, Vardeny says, bring the dream of a spintronic transistor one step closer to reality.
For the first time researchers have succeeded in producing what are known as spin wave overtones. The technology paves the way for increasing the data transmission rate of wireless communication.
