This new technology is behind memory applications such as computer hard disks.
Researchers from the Institute of Physics of the Academy of Sciences of the Czech Republic, in collaboration with researchers from Barcelona, Berkeley, and Halle have demonstrated an experimental spin-based microelectronic device using an antiferromagnetic semiconductor compound Sr2IrO4.
Currently, the Academy of Europe has about 3000 members from the physical sciences and technology, biological sciences and medicine, mathematics, humanities, social and cognitive sciences, economics and the law. Besides Tomas Jungwirth, Czech Republic has two other members of this section (Jiří Bičák a Pavel Exner).
Efficient spin-charge and charge-spin converters are needed for future technologies allowing to integrate the so far isolated worlds of semiconductor and magnetic devices.
In order to shake a magnet electrically without involving an electro-magnet or another permanent magnet, one has to step out of the realm of classical physics and enter the relativistic quantum mechanics. Researchers from the Institute of Physics, in collaboration with researchers from Cambridge, Nottingham, and Mainz, have discovered a new physical phenomenon that allows manipulating the state of a magnet by electric fields.
Researchers from the Institute of Physics of the Academy of Sciences of the Czech Republic, in collaboration with researchers from Berkeley and Barcelona, have demonstrated that it is possible to use another type of magnetic materials, the so-called antiferromagnets to store information. Antiferromagnetic materials are magnetic inside, however, their microscopic magnetic moments sitting on individual atoms alternate between two opposite orientations.
The Spintronics and Nanoelectronics group from the Institute of Physics, Academy of Sciences of the Czech Republic has contributed to the discovery of new mechanisms for storing information.
A discovery of a relativistic effect, to which contributed also researchers from the Institute of Physics of the CAS, was published in Nature Photonics and Nature Communications.
In the near future, it is expected that the development of spintronic provides high density magnetic random access memories and logic-in-memory architectures, opening a route to the new generation of high-speed, low-power instant on-and-off computers.
The discovery, allowing to manipulate spins in a magnet by short laser pulses, was reported by scientists from the Joint Laboratory of Opto-Spintronics at the Faculty of Mathematics and Physics, Charles University and the Institute of Physics, Academy of Sciences.
The discovery is a result of a longstanding fruitful collaboration of scientists from the Institute of Physics of the Academy of Sciences of the Czech Republic and laboratories in Cambridge and Nottingham in the UK.
The team has engaged recently discovered quantum-relativistic phenomena for both spin manipulation and detection to realize the spin transistor and to demonstrate spin-logic operation.
