| Outline of Final Research Achievements |
We have carried out the syntheses of new superconductors and frustrated magnets by using the ionic liquid and hydrothermal synthesis methods in order to give a breakthrough to the materials search in the strongly correlated electron system. We prepared crystals of Te4[BixCl4] by the ionic liquid synthesis method. Although the previous study reported the superconductivity of the compound, we could not obtain the evidence for this. The hydrothermal synthesis yielded a single crystal of the new kagome antiferromagnet CdCu3(OH)6(NO3)2・H2O (CdK). We found an unconventional magnetic order with a negative vector chirality in CdK. Moreover, a series of magnetization plateaus are observed under ultrahigh magnetic fields up to 160 T, which indicates the formation of magnon crystals on the kagome net.
