A research team led by Kyushu University has developed a new fabrication method for energy-efficient magnetic random-access memory (MRAM) using a new material called thulium iron garnet (TmIG) that has been attracting global ...
Magnetic materials have been known since ancient times and play an important role in modern society, where the net magnetic order offers routes to energy harvesting and data processing. It is the net magnetic moment of ferromagnets ...
Typically, the charge of electrons is used to store and process information in electronics-based devices. In spintronics, the focus is instead on the magnetic moment or on magnetic vortices, so-called skyrmions—the goal ...
An international team of researchers from Forschungszentrum Jülich (Germany), Tohoku University (Japan), and École Polytechnique de Montréal (Canada) has made a significant discovery in semiconductor science by revealing ...
Ferrimagnets are a special type of magnet where different atoms' magnetic moments partially cancel each other out, creating a rich internal structure. They are widely used in technologies from magneto-optical devices to spin-based ...
In a world-first, researchers from the Femtosecond Spectroscopy Unit at the Okinawa Institute of Science and Technology (OIST) have directly observed the evolution of the elusive dark excitons in atomically thin materials, ...
When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the momentum of light when it enters ...
Transistors, the building blocks of modern electronics, are typically made of silicon. Because it's a semiconductor, this material can control the flow of electricity in a circuit. But silicon has fundamental physical limits ...
The field of ultrafast magnetism explores how flashes of light can manipulate a material's magnetization in trillionths of a second. In the process called all-optical switching (AOS), a single laser pulse of several femtoseconds ...
A research team from the University of Chemistry and Technology, Prague (UCT Prague) and the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences (IOCB Prague) has created and described a new type ...
