Research Abstract |
We have found various exotic quantum phenomena in 1D, 2D and 3D quantum frustrated systems, derived from competing antiferromagnetic and ferromagnetic interactions. 2D systems (CuX)An-1BnO_<3n+1> show novel phases such as a ferromagnetic Shastry-Sutherland spin singlet state ((CuCl)LaNb2O7) and a quantized magnetization state ((CuBr)Sr_2Nb_3O_<10>), and quantum phase separation. 1D system LiCuVO_4 exhibits an unprecedented magnetic state related to nematic state. 3D K_2Cr_8O_<16> exhibits a ferromagnetic metal to ferromagnetic insulator transition that is explained in terms of Peierls mechanism, and a theoretically predicted random fan out state is realized in Sr(Fe,Mn)O_2.
