The magnetic helicoidal dichroism, obtained through the interaction of an extreme ultraviolet vortex beam carrying orbital angular momentum with a magnetic vortex, has been experimentally observed. Numerical simulations based on classical electromagnetic theory show that this dichroism is based on the interference of light modes with different orbital angular momenta, which are populated after the interaction between light and magnetic topology. This observation sets the framework for the development of new tools to investigate ultrafast magnetization dynamics.
