https://phys.org/nanotech-news/nano-physics/ en-us The latest science news on nanophysics, nanotechnology, nanotech and nanoscience. Magnetic switching processes are considered a prime example of controllable physics at the nanometer scale: in certain thin-film systems, a short electrical current pulse is sufficient to reverse the magnetization in a targeted way. The underlying effect is the so-called spin–orbit torque: the current exerts a force on the magnetic moments in the material and can thus flip them in a controlled manner. This effect is expected to enable new data storage and computing architectures in the future. https://phys.org/news/2026-05-chaos-turbulent-birth-magnetic-nanovortices.html Nanophysics Sun, 24 May 2026 16:00:01 EDT news698669668 A German–Israeli research team led by Dr. Andreas Furchner has demonstrated how imaging ellipsometry enables non-destructive characterization and quality control of microstructured MXene thin films during device fabrication.
