论文摘要
我们报告了Quais-1D铁粉红色Irchcogogenide的合成和物理性质研究$ \ rm bafe_2se_4 $，该研究共享了$ \ rm fese_4 $ tetrahedra建筑图案，通常在铁粉红色的粉红色果发基元中通常看到。通过固态反应法实现了高质量的多晶样品，并通过X射线衍射，电阻率，磁化率和中子衍射测量值来表征。 $\rm BaFe_2Se_4$ is a narrow gap semiconductor that magnetically orders at $\sim$ 310 K. Both neutron powder diffraction results and isothermal M-H loops suggest a canted antiferromagnetic structure where Fe sublattice are antiferromagnetically ordered along the c-axis quasi-1D chain direction, resulting in a net ferromagnetic moment in the沿着A轴的垂直方向向B轴倾斜的角度为18.7 $^\ circ $。
We report the synthesis and physical properties studies of quais-1D iron chalcogenide $\rm BaFe_2Se_4$ which shares the $\rm FeSe_4$ tetrahedra building motif commonly seen in the iron chalcogenide superconductors. A high-quality polycrystalline sample was achieved by solid-state reaction method and characterized by X-ray diffraction, electrical resistivity, magnetic susceptibility and neutron diffraction measurements. $\rm BaFe_2Se_4$ is a narrow gap semiconductor that magnetically orders at $\sim$ 310 K. Both neutron powder diffraction results and isothermal M-H loops suggest a canted antiferromagnetic structure where Fe sublattice are antiferromagnetically ordered along the c-axis quasi-1D chain direction, resulting in a net ferromagnetic moment in the perpendicular direction along the a-axis with tilted angle of 18.7$^\circ$ towards the b-axis.
