A promising approach for speeding up data storage devices consists of switching the magnetization, or the electrons’ spin, of magnetic materials with ultra-short femtosecond laser pulses. But, how the spin evolves in the nanoworld on extremely short time scales, in one millionth of one billionth of a second, has remained largely myst...

source:MINING.COMResearchers at the Korea Institute of Materials Science (KIMS) have developed rare-earth-saving permanent magnets that can replace the 42M-graded commercial magnets while reducing the amount of neodymium by about 30%. The domestic market for rare-earth permanent magnets for high-efficiency motors was worth $186 billion per year in 2021, and Korea depends on imports of the material. In a paper published in the journal Scripta Materialia, the researchers say the technology achieved the commercial level of performance currently used in the industry, even though the amou...

source:news wiseNewswise — A research team led by the Georgia Tech Research Institute (GTRI) was recently selected for second-phase funding of a $9.2 million project aimed at demonstrating a hybrid computing system that will combine the advantages of classical computing with those of quantum computing to tackle some of the world’s most difficult optimization problems.Over the next two years, the team plans to use several hundred quantum bits (qubits) made of trapped ions to put the unique capabilities of quantum computing systems to work on these challenges. The team, which also includes resea...
