提出了一种碱土金属钯酸盐CaPd_3O_4晶体生长的新方法。在熔融氯化物溶剂中,在施加电压的电极上合成晶体。晶体的最大长度约为1.5mm,X射线衍射数据采用Pmn空间群的立方结构进行了很好的修正,晶格常数a为5.7471(10)?电阻率的温度依赖性表现出类似于超导体的特性,在低温下具有非常小的激活能Ea为0.45 meV,并且在300 K下的电阻率为0.1 cm。磁化率随温度的变化表现为Curie-Weiss顺磁行为,其居里常数Cmol为5.0(1)× 10- 3emuK/(molOe),表明存在局域自旋磁矩。
A new method for the crystal growth of alkaline-earth palladate CaPd3O4 was developed. The crystals were synthesized on a voltage-applied electrode in a molten chloride solvent. The maximum length of the crystal was about 1.5 mm. The X-ray diffraction data were refined well by assuming a cubic structure of the space group Pm n, and the lattice constant a was 5.7471 (10) ?. The temperature dependence of the resistivity showed semiconductor-like characteristics with a very small activation energy Ea of 0.45 meV at low temperatures, and the resistivity at 300 K was 0.1 cm. The temperature dependence of the molar magnetic susceptibility showed the Curie-Weiss paramagnetic behavior with a small molar Curie constant Cmol of 5.0(1) × 10-3 emu K/(mol Oe), indicating the existence of localized spin moments.
