"visualize and control the rotation of handful of spins arranged in vortex-like texture, a kind of spin "nano-whirlpool" called a skyrmion... arranging laser pulses apart just right to control rotation of spins in Cu2OSeO3... can switch their orientation by changing delay time between successive driving pulses and adjusting laser polarization... transmission electron microscope to visualize spin changes.. can advance spintronics, including new types of computer memory, logic gates, and high-precision sensors"
