ABO_3型稀土复合氧化物由于其具有特殊的电、磁性质,良好的催化性能及气敏性能,在固体物理及固体化学领域中受到人们的重视,ABO_3型稀土镓酸盐体系便是其中之一,它在发光等方面有自己的特点.钒是有广阔应用前景的过渡元素之一,作为取代离子形成LnGa_(1-x)V_xO_3化合物尚未见报道.因此本文着重对这类化合物中钒离子的价态及钒取代镓对化合物结构,磁性的影响进行探讨,从而进一步了解稀土元素的近邻环境与化合物性质之间的相关规律. ABO_3-type rare earth composite oxides have attracted people’s attention in the fields of solid state physics and solid state chemistry due to their special electric and magnetic properties, good catalytic performance and gas sensitivity. ABO 3 -type rare earth gallate system is one of them , Which has its own characteristics in the aspects of luminescence, etc. Vanadium is one of the transitional elements with broad application prospects and has not been reported as a substituted ion for forming LnGa_ (1-x) V_xO_3 compounds.Therefore, in this paper, Valence and vanadium substitution of gallium on the structure and magnetism of the compounds were discussed in order to further understand the correlation between the adjacent environment of the rare earth elements and the properties of the compounds.
