| 中文摘要 | The 6H BaRu1-xMnxO3 with the hexagonal BaTiO3 structure was synthesized using high-pressure sintering method. It is found that the lattice parameter deviates from Vegard's law at x = 0.3 for the solid solutions due to the charge transfer effects at B-site. The Substitution of Mn for RU cations gives rise to the short-range magnetic ordering, due to the disordered arrangement of Ru and Mn cations. The compounds are weak ferromagnetic in the x range 0.05-0.40, with the maximal Curie temperature T-c 175.2 K at x = 0.10. They are of spin-glass-like magnetism at lower temperature at x >= 0.1. With Mn doping, the 6H BaRuO3 transforms to a semiconductor from the primal metal at x = 0.30. The resistance as a function of temperature below about 70K follows the two-dimensional variable-range hopping conduction mechanism in BaRu0.50Mn0.50O3. (C) 2008 Elsevier Inc. All rights reserved. |
