The study of terahertz (THz) spin dynamics in antiferromagnetic systems explores the fastest magnetic excitations possible in materials whose sublattice magnetisations cancel in equilibrium. In these ...

However, the scope of what is possible extends much further: More recent approaches aim at using not just individual spins, but entire spin waves made up of partly hundreds of trillions of spins. Such ...

Researchers have developed a pioneering method to precisely manipulate ultrafast spin waves in antiferromagnetic materials using tailored light pulses. As demands for computing resources continue to ...

Atomic-scale defects in 2D materials show terahertz spin splitting, pointing to robust spin qubits and single-photon emitters at higher temperatures. (Nanowerk News) Scientists from the National ...

Scientists from the National University of Singapore (NUS) have discovered that atomic-scale substitutional dopants in ultra-thin two-dimensional (2D) materials can act as stable quantum systems ...

The increasing demand for denser information storage and faster data processing has fuelled a keen interest in exploring spin currents up to terahertz frequencies. The emergent two-dimensional ...

Researchers report a nonvolatile phase-programmable spintronic terahertz emitter that uses femtosecond laser pulses to switch THz phase states and magnetic fields to reset them. The device enables ...

An international research team has developed a new method for the efficient coupling of terahertz waves with much shorter wavelengths, so-called spin waves. Their experiments, in combination with ...

It’s a well-known fact that anti-ferromagnetic materials are called that way because they cannot be magnetized, not even in the presence of a very strong external magnetic field. The randomized spin ...

(Nanowerk News) The flow of matter, from large-scale water currents to the microscopic flow of electric charge, is fundamental to the infrastructure of modern society. Scientists are constantly ...

New ultrafast method for controlling magnetic materials might enable next-generation information processing technologies. This illustration shows that a pair of intense THz laser pulses drives spin ...
