Disclosed is a system (10) for generating skyrmions, including: a gun (12) including a wall-forming region (14) made from a first material, the region (14) defining an outer space (16) made from a second material different from the first material and an inner space (18) made from a third material different from the first material, the second material and the third material being magnetic materials; and a magnetization reversal device (26) that can reverse the magnetization at the interface between the region (14) and the inner space (18).
