本文分别用固相反应法和化学共沉淀法制备了SrRuO3样品。对样品的结构、颗粒尺寸、磁学性质、输运性质作了研究。X射线衍射实验表明样品均为单相钙钛矿结构氧化物,用扫描电子显微镜(SEM)观察了样品晶粒形貌,用振动样品磁强计(VSM)和Quantum Design PPMS 9系统测量了样品的磁性能。使用Quantum Design PPMS 9系统和牛津公司制造的多用途测量系统(Maglab Exa Measurement System)测量了样品的输运性质。
In this paper, SrRuO3 samples were prepared by solid-state reaction and chemical coprecipitation. The structure of the sample, particle size, magnetic properties, transport properties were studied. X-ray diffraction experiments showed that the samples were all single-phase perovskite oxides. The morphology of the samples was observed by scanning electron microscopy (SEM) and the samples were measured by vibrating sample magnetometer (VSM) and Quantum Design PPMS 9 system Magnetic properties. The transport properties of the samples were measured using the Quantum Design PPMS 9 system and the Maglab Exa Measurement System manufactured by Oxford Instruments.
