First observation of a square lattice of merons and antimerons

Scientists have, for the first time, observed a square lattice of merons and antimerons -- tiny magnetic vortices and antivortices that form in a thin plate of the helical magnet Co8Zn9Mn3. The ability to manipulate nanometer-scale spin textures such as merons and skyrmions is a key to the development of spintronics -- next-generation electronic devices that are very low in power consumption.
