Scientists Twist X-Rays with Artificial Spin Crystals (IMAGE)
Caption
X-ray photons scattered from a patterned array of nanoscale magnets acquire a twist that is related to orbital angular momentum. The X-ray beams can be switched on and off with temperature and magnetic fields. Inset: experimental X-ray diffraction pattern
