PAGE 106 Selected Applications attoAFM I Helimagnetic Phase of Fe 0.5 Co 0.5 Si 1µm 1µm Real space imaging of exotic magnetic phases provides a level of understanding that cannot be achieved with indirect techniques. The figure on the left shows one of the first observations of a helimagnetic phase using the attoMFM I. The periodicity of the stripes is around 100 nm. This phase is of particular interest because of its proximity to a skyrmion phase. Skyrmions are exotic magnetic excitations, studied extensively because of their potential use in spintronic applications. The measure- ment was performed on a FeCo 0.5 Si 0.5 sample at 4 K using an attoMFM I in attocube application labs. (attocube application labs, 2013; sample courtesy of A. Bauer and C.
