000859536 520__ $$aThe concept of chirality, meaning left- or right-handedness, plays an essential role in symmetry properties of nature at all length scales from elementary particles to cosmic science. In material sciences, it is very important to understand the chirality in molecules, crystals and magnetic structures both from theoretical and experimental points of view. Chiral helimagnetic ordering, forming only right- or left-handed spiral magnetic structure, has attract much attention in the last time due to unique magnetic textures such as skyrmion and chiral magnetic soliton lattice [1, 2]. Therefore, it is very important to investigate the interplay between crystallographic and helimagnetic chirality. However, only very few experimental results on this interplay are reported up to now, due to the difficulty to synthesize homo-chiral single crystals, which consisting solely of right- or left-handed crystalline domains.Using novel two-step crystallization technique under stirring we succeeded in obtaining the cm-large ordered homo-chiral single crystals of CsCuCl3 with desired handedness [3]. Circular-polarized synchrotron radiation at SPring 8, J-Park was employed to determine the handedness of the crystal symmetry in different samples [4]. Below 10.5 K a proper-screw magnetic order with propagation vector k=(1/3,1/3, ±δ) with (δ ∼ 0.09) is formed in CsCuCl3. The magnetic chirality of the homo-chiral crystals was investigated using polarized single crystal diffractometer POLI at MLZ. Our experimental results revealed that the handedness of the magnetic helicity is coupled and directly controlled by the crystallographic lattice chirality [5]. The results could be understood in terms of Dzyaloshinskii-Morya interaction strongly coupled to the lattice, lifting the helix chiral degeneracy.References:1. S.
