摘要

非范德华二维材料由于其在磁性、催化和光电应用中的激发约束增强特性而越来越受欢迎。由于剪切能非常低,最近发现非范德华材料沿解理面发生机械和液体剥离,这令人鼓舞,并为进一步探索具有特殊性能的非范德华物质开辟了途径。在此,我们通过在有机溶剂中的液相剥离,成功地从大块矿石中分离出了几层磁黄铁矿(Fe7S8)纳米片,并研究了大块和剥离样品的磁性有序性。实验和第一性原理理论研究都指出了约束诱导的从铁磁单斜晶(4M)到反铁磁六方晶(3T)的磁结构相变,其特征是抑制了Besnus跃迁。

Magneto-structural Phase transition in Exfoliated Pyrrhotite (Fe7S8) Ultra-thin Sheets
Non-van der Waals two-dimensional materials are gaining popularity due to their exciting confinement-enhanced properties for magnetic, catalytic, and optoelectronic applications. The recent discovery of mechanical and liquid exfoliation of non-van der Waals materials along the cleavage planes, owing to the very low scission energies, is encouraging and opens the avenue for further exploration of non-van der Waals materials having exceptional properties. Herein, we successfully isolated a few layers of Pyrrhotite (Fe7S8) nanosheets from bulk mineral ore by means of liquid phase exfoliation in organic solvent and studied the magnetic ordering at bulk and exfoliated samples. Both experimental and first principle theoretical investigations point out confinement-induced magneto-structural phase transition from ferromagnetic monoclinic (4M) to antiferromagnetic hexagonal (3T) characterized by the suppression of Besnus transition.
