Outline of Final Research Achievements |
With introducing our unique crystallization technique, we obtained large homo-chiral single crystalline samples of CsCuCl3. We performed polarized neutron diffraction experiments of CsCuCl3 for investigating interplay between crystalline and helimagnetic chirality. With use of our homo-chiral single crystal, we successfully observed the interplay of these chiralities due to Dzyaloshinskii-Moriya interaction. And, we prepared a micrometer-sized single crystal of CrNb3S6, and successfully observed discrete changes in magnetoresistance due to formation of chiral magnetic soliton lattice.
