La_（2-x）Sr_xMnO_4的结构、物性及电荷有序研究和新超导体Na_xCoO_2·yH_2O的电化学合成
|
摘要
对214结构的La2-xSrxMnO4（1.125≤x≤2.0）的结构、物性及电荷有序进行了较系统的研究。对于其晶胞参数的非线性变化提出了一个解释的模型，这个模型考虑了电荷、轨道和晶格间的相互作用；磁性研究中，在x=1.75的样品中，首次观察到在44K左右可能存在自旋玻璃转变；在电阻研究中，发现其电阻随温度的变化规律可以用热激发导电机制很好的拟合；在1.5≤x≤1.75的样品中观察到电荷有序现象，并做出了相应的解释。
电化学方法在材料物性研究过程中是一种很重要的处理方法，精确控制电化学处理过程中的各种参数是非常必要的。为此，开发了能精确控制电化学处理参数的电化学实验控制软件PSMMCP。
NaxCoO2·yH2O是新型超导材料，虽然Tc值只有5K左右，但在理论上具有很重要的意义；制备该材料中使用的剧毒物质限制了研究工作的进一步开展，利用已开发的电化学控制软件对该材料的合成方法进行了初步的探索，获得了一定的结果。
1. Structure, Physical Properties and Charge Ordering in La2-xSrxMnO4 (1.125≤x≤2.0)。Intensive studies have been conducted on colossal magnetoresistance (CMR) material with AMnO3 (A=Alkaline earth and rare earth elements) perovskite structure since 1993, and comparatively less attention was focused on their close derivatives with the K2NiF4 structure showing a quasi-two dimensional character. In this paper, a systematical research was done on the La2-xSrxMnO4 material with the K2NiF4 structure. Structural measurements have revealed the nonlinear changes of lattice parameters in the manganites La2-xSrxMnO4 with the increase of Sr content, and these changes can be well understood by means of interactions among the charge, crystal lattice and the orbital degree of freedom in this system. A probably spin-glass transition was detected for the first time in the x=1.75 sample at the temperature of around 44K. Fundamental properties of charge ordering appearing in the range of 1.5≤x≤1.75 have been observed at low-temperatures and interpreted in terms of the Mn3+-dz2 orbital ordering.
2. In order to control the parameters (including voltage, current, etc.) in electrochemical experiment precisely, The software PSMMCP (Power Supply and MultiMeter Controlling Program) was developed.
3. NaxCoO2·yH2O was a new superconductor reported firstly in March 2003. Although the Tc was only about 5K, it has attracted much attention for theoretical importance because there is no Cu-O layer in it. Primary research was done on it by electrochemical method with the software PSMMCP. Primary result was obtained and the more research is under way.
