What is it about?
Skyrmions, i.e. magnetic bubbles, are a potential data carrier for energy efficient, magnetism based, computing devices. Commonly skyrmions that are moved along a track by current pulses do not move straight but under an angle, the skyrmion hall angle. We have shown that the velocity of skyrmions and also the skyrmion hall angle can be drastically influenced by irradaition of the hosting material with Ga+ ions.

Why is it important?
Skyrmion computing is thought to be very power efficient. Controlling the motion of skyrmions is a key factor to utilize them for logic systems. Thus we open the door to a whole new concept of skyrmion control.
