We investigate magnetic superlattices based on the low-damping and high saturation magnetization binary alloy Co25Fe75. The formation of stable sub-100 nm diameter skyrmions is confirmed and analyzed by magnetic force microscopy within an Keff <0 . The relatively low damping of the superlattice spin dynamics is quantified by broadband ferromagnetic resonance measurements.
