| Outline of Final Research Achievements |
The concept of left and right symmetry plays an important role in all areas of natural science. In this project, we have studied unique class of magnetic crystal where the left-right symmetry is broken. In this class of magnet, called chiral helimagnets, are expected to have inexhaustible functionality that directly reflects the symmetry breaking. During the period of this project, we made out two problems. First, we made clear "global phase diagram of mono-axial chiral helimagnet", and second "resonant dynamics of the chiral soliton lattice confined to a finite region". These achievements is an important milestone in the field of chiral magnetic research that seems to still continue.
