TY - JOUR PY - 2006// TI - Real-space observation of helical spin order JO - Science A1 - Uchida, M. A1 - Onose, Y. A1 - Matsui, Y. A1 - Tokura, Y. SP - 359 EP - 361 VL - 311 IS - 5759 N2 - Helical spin order in magnetic materials has been investigated only in reciprocal space. We visualized the helical spin order and dynamics in a metal suicide in real space by means of Lorentz electron microscopy. The real space of the helical spin order proves to be much richer than that expected from the averaged structure; it exhibits a variety of magnetic defects similar to atomic dislocations in the crystal lattice. The application of magnetic fields allows us to directly observe the deformation processes of the helical spin order accompanied by nucleation, movement, and annihilation of the magnetic defects.
