概要
- 論文の詳細を見る
For Ag_2Cu_2O_3, the close coupling of the crystal distortion to the magnetic ordering which takes place at 70K has been found by X-ray and neutron diffraction analyses and magnetic measurements. The system has a pyrochlore-related structure with corner-sharing tetrahedra of Cu^<2+> ions, in which the geometrical frustration is inherent. We show how the structural distortion releases the frustration, stabilizing the ordered state of Cu spins (S=1/2). The magnetic susceptibility and specific heat of Ag_2Cu_2O_4 have also been measured. The results indicate that the system is nonmagnetic.
