以Tb4O7、Fe(NO3)3.9H2O、硝酸(1:1)为原料,在柠檬酸体系中用溶胶凝胶法合成了具有钙钛矿结构的稀土复合氧化物TbFeO3;用XRD、TEM对产物的组成、颗粒、大小、形貌进行了表征;结果表明,产物为纳米颗粒,平均粒径为21 nm左右,且颗粒均匀。另外以TbFeO3为光催化剂,对多种水溶性染料进行了光催化降解,发现TbFeO3有...
In this study, the structural and electrical properties of TbFeO3 ceramic, prepared by the conventional mixed﹐xide reaction method, are investigated. The compound crystallizes in an orthorhombic crystal system. The multiple valence states of Tb and Fe in the compound are confirmed by X‐ray ...

聚丙烯酰胺凝胶法合成TbFeO_3纳米颗粒及其可见光催化活性
TbFeO3We investigated terahertz (THz) transmission of square-particle and rod structured TbFeO3 metamaterials. Mie-type resonances were excited in TbFeO3-based metamaterials. And their dependence on shape and orientation angle was studied. Dielectric TbFeO3 ceramic wafers, which were prepared by 3...
The results are compared with recent experimental data on TbFeO3 single crystal and Fe3Tb metallic alloy. Our conclusion is that the plateau in the magnetic viscosity observed at low temperatures, and interpreted as quantum tunneling of magnetization, can not be explained by the self-heating.E.B...
We report Mössbauer and magnetisation studies of spin-reorientation transitions in single-crystal samples of TbFeO3 at 4.2 K, induced by fields up to 10 T. Fields were applied along all three crystal axes and various spin-reorientation effects were observed. These may be explained microscopically...
