典型的多铁性材料${mathrm{Ni}}_{3}{mathrm{V}}_{2}{mathrm{O}}_{8}$具有$S=1phantom{rule{0.16em}{0ex}}{mathrm{Ni}}^{2+}$自旋的kagome阶梯结构，因其复杂的磁相图以及自旋序与铁电性之间的相互作用而备受关注。在目前的工作中，我们报告了对 ${mathrm{Ni}}_{3}{mathrm{V}}_{2}{mathrm{O}}_{8}$ 的全面角度相关铁电极化研究，场在低温下在 $ac$ 平面内旋转。当场平行于易磁化轴（$a$ 轴）施加时观察到的沿着晶体 $b$ 轴的低场感应铁电（LF）态，随着场旋转靠近 $c$ 轴而突然消失。特别令人感兴趣的是当场位于 $a$ 和 $c$ 轴之间的小角度范围内时，在高场下观察各种方向的重入铁电 (HF) 相。视场角相图是根据低温角相关偏振结果构建的，由连续的 LF 相和不连续的 HF 相组成，两者都相对于 $a$ 轴呈现对称性。由于戈薇阶梯结构中存在两个解耦亚晶格，这两个相的微观起源不同，其中低场极化被认为源自脊柱自旋的螺旋结构，而高场相则归因于倾斜高磁场下交叉关系的排序。
The canonical multiferroic material ${mathrm{Ni}}_{3}{mathrm{V}}_{2}{mathrm{O}}_{8}$ with a kagome staircase structure of $S=1phantom{rule{0.16em}{0ex}}{mathrm{Ni}}^{2+}$ spins has attracted much attention for its complex magnetic phase diagram, as well as the interplay between spin orders and ferroelectricity. In the present work, we report a comprehensive angular dependent ferroelectric polarization study on ${mathrm{Ni}}_{3}{mathrm{V}}_{2}{mathrm{O}}_{8}$ with the field rotating within the $ac$ plane at low temperatures. The low field induced ferroelectric (LF) state along the crystallographic $b$ axis, which has been observed when the field is applied parallel to the easy axis ($a$ axis), is revealed to vanish suddenly as the field is rotating close to the $c$ axis. Of particular interest is the observation of the reentrant ferroelectric (HF) phase at high field for various orientations when the field is between the $a$ and $c$ axes within a small angle range. The field-angle phase diagrams are built based on the low-temperature angular dependent polarization results and composed of a continuous LF phase and a discontinuous HF phase both exhibiting symmetry with respect to the $a$ axis. The microscopic origins of the two phases are different due to the two decoupled sublattices in the kagome staircase structure, where the low-field polarization is proposed to originate from the spiral structure of the spine spins, while the high-field phase is ascribed to the ordering of the cross-ties under a tilting high magnetic field.
