Strong alternating magnetic fields can be used to generate a new type of spin wave that was previously just theoretically predicted. This was achieved for the first time by a team of physicists from Martin-Luther-Universität Halle-Wittenberg (MLU). They report on their work in the scientific journal “Nature Communications” and provide the first microscopic images of these spin waves.

Together with an internatonal team of colleagues, TRR227 PI J. Berakdar (project B06) and coworkers published their latest results on magnetizing an atomic gas with light in the APS journal Physical Review Letters . The theorists predict that an atomic gas could be magnetized using high-power lasers with patterned wavefronts, something that could provide a noninvasive way to quickly manipulate the magnetic properties of the gas. The paper was recently highlighted on the front cover of the Vol. 128, Issue 15, 15 April 2022 . In addition, it was covered by a Synopsis in Physics with the title " Magnetizing an Atomic Gas with Light ".

Recent results published in Phys. Rev. X: Researchers of the Collaborative Research Center TRR227 “Ultrafast spin dynamics” at Freie Universität Berlin found that the magnetization of laser-excited ferromagnetic iron undergoes the same dynamics independent of the wavelength of the driving laser pulse. Therefore, it is just the amount of heat dumped into the electrons at a given moment that determines the course of the demagnetization.
