The key to creating spintronics devices is the ability to effectively manipulate, and measure, a single skyrmion. Researchers in Japan used a thin magnetic plate made up of a compound of cobalt, zinc, and manganese, Co9Zn9Mn2 to observe the dynamics of a single skyrmion at room temperature. They were able to track the motions of the skyrmion and control its Hall motion directions by flipping the magnetic field when they subjected it to ultrafast pulses of electric current—on the scale of nanoseconds. They found that the skyrmion’s motion demonstrated a dynamic transition from a pinned static state to a flow motion by way of creep motion under the stimulus of electric current, and quantified the relatively fast velocity of the skyrmion, over 3 meters per second. According to the researchers their work may lead to further studies of dynamics of various topological spin textures, leading to the development of skyrmion-based devices…read more.
