We express our sincere appreciation to Y. Togawa and J. Kishine for fruitful discussions. This work was supported by JSPS KAKENHI Grants No. 25220803, No. 25390139, No. 26108719, No. 15H03680, No. 15H05885, No. 15H05886, No. 16KK0102, 17H02912, No. 17H02767, and No. 17H02815. K.K. acknowledges the support by the Helmholtz International Fellow Award. J.C. acknowledges Grant No. MAT2015-68200-C2-2-P from the Spanish Ministry of Economy and Competitiveness. The synchrotron radiation experiments were performed at the BL39XU of SPring-8 with the approval of the Japan Synchrotron Radiation Research Institute (JASRI) (Proposals No. 2009A1607 and No. 2009B1586). The neutron experiments at the MLF of the J-PARC were performed under user programs (Proposals No. 2013A0166, No. 2013B0108, No. 2014A0085, and No. 2014B0165). Part of the work is based upon experiments performed at the POLI instrument, which is operated by RWTH Aachen University and Forschungszentrum Jülich GmbH (Jülich Aachen Research Alliance JARA).

N2 - We report a crystal growth method to obtain homochiral single crystals of CsCuCl3 and polarized neutron diffraction studies to examine the chiral helimagnetism of this compound. The homochiral crystals were grown by two-step crystallization. First, millimeter-sized seed crystals were synthesized by spontaneous crystallization with stirring. The handedness of the seed crystals was determined by x-ray diffraction. Then, centimeter-sized homochiral crystals were obtained from the selected homochiral seed crystals. The large homochiral crystals made it possible to perform polarized neutron diffraction. We clarified a strong correlation between the crystal and magnetic chiralities, which governs the nature of antisymmetric Dzyaloshinskii-Moriya interactions.
