| 摘 要： | 为了寻求新的非常规多铁性材料,采用固相合成方法制备具有Ruddlesden-Popper结构的(1-x)Sr_3Sn_2O_7+x Ca_3Mn_2O_7(SSO+CMO)(x=0,0.05,0.10,0.15,0.20)系列陶瓷.通过X射线衍射、紫外可见光谱和磁性测量,发现SSO+CMO陶瓷为单一正交相结构,空间群为A21am.随着掺杂量x的增加,样品的晶胞参数和体积相应地减小;在室温不同频率下,样品的介电常数和介电损耗随着频率增加而减小,且在x=0.1时有弱的铁磁性.

| Abstract: | In order to obtain new hybrid improper ferroelectricity, the (1-x)Sr3Sn2O7+xCa3Mn2O7 (0 ≤ x ≤ 0.2) samples each with a Ruddlesden-Popper phase are prepared by the conventional solid-state reaction method. The phase purity is characterized by X-ray diffraction through using the GSAS refinement. The results indicate that (1-x)Sr3Sn2O7+xCa3Mn2O7 sample has an orthorhombic structure and its cell constants decrease with content x increasing. At room temperature, the dielectric constant decreases with frequency increasing. Sr3Sn2O7 exhibits diamagnetism. With increasing the content of Ca3Mn2O7, the sample presents diamagnetism, paramagnetism, weak ferromagnetic and paramagnetism in sequence. And the sample with x=0.1 has a weak ferromagnetic property. All these pave a way for selecting Ruddlesden-Popper multiferroic materials. |
