| The BiCr0.5Ni0.5O3 perovskite has been obtained at high pressure. Neutron and synchrotron diffraction data show a Pnma orthorhombic structure with a = 5.5947(1) Å, b = 7.7613(1) Å, and c = 5.3882(1) Å at 300 K and random B-site Cr/Ni distribution. Electron diffraction reveals an incommensurate modulation parallel to the b axis. The combination of either Cr?O?Ni (J > 0) or Cr?O?Cr/Ni?O?Ni (J < 0) nearestneighbor spin interactions results in a random-bond spin-glass configuration. Magnetization, neutron diffraction, and muon-spinrelaxation measurements demonstrate that variations in the local bonding and charge states contribute to the magnetic frustration | |
