研究了层状钙钛矿钴氧化物Y1-xG出BaCo2O5(x=0,0.25,0.5,0.75,1)的结构和输运性质,结果显示它们具有相似的相变行为,从而证明GdBaCo2O5与YBaCo2O5一样,也存在电荷有序转变.结果还表明电荷有序转变温度随稀土离子半径增加而上升.
The structural and transport properties of the layered cobalt oxide Yl-xGdxBaCo20s (x= 0,0. 25,0. 5, 0. 75,1) were investigated. From the evolution of the behavior between YBaCo2O5 and GdBaCo2O5 we have confirmed the existence of charge-ordering transition in GdBaCo2O5. It is also shown that the charge-ordering transition temperature rises with increasing the ionic radius o{ rare earth.
