摘要：
The orthorhombic rare-earth cobaltate Nd0.67Sr0.33CoO3 is studied by neutron powder diffraction. The Co sublattice orders ferromagnetically below T(c)approximate to 200 K with the magnetic moments aligned along the c axis. On cooling, Nd0.67Sr0.33CoO3 revealed an induced ferromagnetic order of the Nd sublattice coupled antiparallel to the Co lattice. Within a simple spin-only picture. steric considerations give evidence for a mixed-valent mixed-spin configuration of the Co ions. This is compared to an intermediate valence-state scenario that shows the necessity of detailed electronic-structure calculations.
