摘要
(La,Sr)14Cu24O41的结构中包含一维的CuO2链和Cu2O3梯子,在室温以下Cu2O3梯子对磁化率的贡献很小,实验测量的磁化率反映了CuO2链的磁性,是研究一维磁性的理想材料。研究了非磁性的Zn2+替代Cu2+和Sr2+替代La3+对La6Sr8Cu24O41中CuO2链磁性的影响。
The structure of (La, Sr)_(14)Cu_(24)O_(41) contains one-dimension CuO_2 chain and Cu_2O_3 ladder. Below room temperature, Cu_2O_3 ladder has a little contribution to magnetic susceptibility and susceptibility measured represents the magnetic property of CuO_2 chain. It is ideal material for investigations of one-dimension magnetic property. The effects of non-magnetic Zn^(2+) substitution for Cu^(2+) and Sr^(2+) substitution for La^(3+) on the magnetic properties of CuO_2 chain in La_6Sr_8Cu_(24)O_(41) were studied.
