    A new method of IT technology: using spin waves as data storage, may one day make computers and smartphones more efficient and reliable calculations
    .
    This is the conclusion drawn by the research teams of Martin Luther University and Lanzhou University based on the simulation of spin waves in structural materials

    .
    The research was published in the journal "npj Computational Materials"

    .

    Logic operations including addition, multiplication, and subtraction form the basis of all computing applications on devices such as smartphones and computers
    .
    "Without these operations, we cannot use the stored data," explains Professor Jamal Berakdar from the MLU Institute of Physics

    .
    So far, logic operations have been carried out with the help of charge currents

    .
    However, this technology also has some drawbacks: "The moving charge is sensitive to external electric or magnetic fields

    .
    Energy dissipation is also increasing-the smaller the device, the more the material heats up," Berakdar said

    .
    Therefore, researchers have been looking for alternative methods

    .
    The Magnos tried to use the so-called Magnos

    .
    Magnetons are waves that can be generated in magnetic materials, so they are also called spin waves

    .
    They are generated by magnetization oscillation and can be used as signals in data processing

    .
    Unlike the logic operation assisted by charge and current, electrons do not need to move in information processing based on magnetism, so they consume less energy

    .

    "So far, research on horse grid and spintronics has focused on traditional ferromagnets," Berakdar said
    .
    However, research teams from Germany and China have found that nanostructured antiferromagnetic wires are particularly suitable for logic operations

    .
    "Antiferromagnets are fundamentally different from ferromagnets

    .
    At the microscopic level, they are magnetically ordered, but in such a way, the material as a whole is not magnetized

    .
    Therefore, antiferromagnets respond very well to electric or magnetic fields.
    Weak," Berakdar explained

    .
    The simulations performed by physicists have shown that there are special magnetons in the nano-structured antiferromagnetic wires, which can perform logic operations quickly and reliably at the same time without consuming a lot of energy
