| Research Abstract |
We have explored various ways to control magnetic texture in chiral magnetic crystal by using external fields or electric currents. As a result, we pointed out that crystal chirality causes macroscopic spin chirality in the form of chiral helimagnetic structure. By applying the magnetic field perpendicular to the helical axis, we have a new type of spin texture called magnetic kink crystal or chiral spin soliton lattice. We have made clear that this state has possibility to carry magnetic information, cause magneto-resistance, and electromotive force.
