    Raman scattering study of phase transitions inCs1x(NH4)xH2AsO4mixed crystals
    摘要:
    Temperature dependence of Raman scattering spectra in the cesium-ammonium dihydrogen arsenate (CADA-x, x=0.20) mixed crystal was observed to study anomalies associated with the dipole glass freezing phenomena in the system. A(1) symmetry internal vibrations of arsenate ions were found to deviate from the normal temperature dependence of the third and fourth order anharmonic phonon-phonon interactions at around T(f)similar or equal to 80 K, which was ascribed to the onset of the short range random potential fixing of protons. The B-2 symmetry soft mode derived from the harmonic oscillator coupled mode analysis was found to be a relaxational type characterized by omega(2)/gamma(proportional to)(T-T-o) with T(o)similar or equal to 28.8 K, where omega(2)/gamma corresponds to the relaxation bandwidth of the soft mode. The large difference between the two anomaly temperatures was attributed to the enhanced effective piezoelectric constant associated with the electrostrictive contributions from the random local cluster polarizations.

    二氢砷酸钾,rub和铯晶体的非弹性中子散射,红外吸收和拉曼散射的振动研究:与二​​氢砷化Comparison的比较
    摘要:
    在20–4000 cm -1范围内进行了多晶钾,rub和二氢砷化铯KH 2 AsO 4 RbH 2 AsO 4和CsH 2 AsO 4的振动研究。在20 K处获得的非弹性中子散射光谱可以精确分配OH振动。分析了顺电相和铁电相的红外吸收光谱和拉曼散射光谱。这三种化合物与KH 2 PO 4同构。将结果与二氢砷化T TlH 2 AsO 4的结果进行比较。在所有化合物中,质子动力学似乎都与重原子运动弱耦合。T c处的有序无序跃迁与四方钾、,和铯二氢砷酸根中阴离子和质子的关系运动以及单斜derivative衍生物中阴离子的集体重取向运动有关。光谱特征表明阳离子K t,Rb +和Cs +在两个相中都参与了三维晶格的动力学。相反,重阳离子Tl +运动与氢键层的动力学解耦。没有观察到晶格有序与OH拉伸波数之间的相关性。
