摘要：
我们报道了新合成的$\boldsymbol{TbTi_3Bi_4}$单晶的磁学性质，其晶体结构以铽基锯齿链与钛基笼目晶格的堆叠为显著特征。由于晶场效应使$\boldsymbol{Tb^{3+}}$磁矩沿锯齿链方向排列，该化合物表现出极强的易轴磁各向异性。受强单离子各向异性与多重磁相互作用的共同影响，$\boldsymbol{TbTi_3Bi_4}$表现为准一维伊辛磁体，在$T_\boldsymbol{N}$=20.4 K处存在显著的反铁磁有序。当沿锯齿链方向施加磁场时，在1/3磁化平台与其他磁化平台之间会发生多次变磁转变。我们构建了磁场-温度相图，并确定了由阻挫导致的复杂磁结构。
英文摘要：
We report the magnetic properties of newly synthesized, single crystals of $\mathrm{TbTi_3Bi_4}$ whose crystal structure is highlighted by the stacking of terbium-based zigzag chains and titanium-based kagome lattices. This compound demonstrates extreme easy-axis magnetic anisotropy due to the crystalline-electric-field effect which aligns the $\mathrm{Tb^{3+}}$ moments along the zigzag chain direction. As the result of the strong single-ion anisotropy and multiple magnetic interactions, $\mathrm{TbTi_3Bi_4}$ behaves as a quasi-one-dimensional Ising magnet with a remarkable antiferromagnetic ordering at $T_\mathrm{N}$ = 20.4 K. When a magnetic field is applied along the direction of the zigzag chain, multiple meta-magnetic transitions occur between 1/3 and other magnetization plateaus. We have created a field-temperature phase diagram and mapped out the complex magnetic structures resulting from frustration.
