论文摘要
我们提出了一项关于涡旋物质的全面研究，并在FESE $ _ {1-x} $ s $ _X $系统中固定了具有各种掺杂学位的系统。研究了硫取代对涡旋固定和峰值效应发生的影响。我们表明，在FESE $ _ {1-X} $ S $ _X $系统中，各种固定贡献之间存在复杂的相互作用。此外，我们研究了可能的涡流液体涡流玻璃/晶格过渡，并找到证据表明FESE中的涡流液体 - 涡流玻璃相变具有准二维性质。我们研究了FESE $ _ {1-x} $ s $ _x $系统中的上部临界场行为，发现上临界场高于werthamer-helfand-hohenberg（WHH）模型所预测的临界场，而其温度依赖性可以安装在两个频段的框架中。最后，提出了详细的H-T相图。
We present a comprehensive study of vortex matter and pinning evolution in the FeSe$_{1-x}$S$_x$ system with various doping degree. The influence of sulphur substitution on vortex pinning and peak effect occurrence is studied. We show that there is a complex interplay among various pinning contributions in the FeSe$_{1-x}$S$_x$ system. Additionally, we study a possible vortex liquid-vortex glass/lattice transition and find an evidence that the vortex liquid-vortex glass phase transition in FeSe has a quasi two-dimensional nature. We investigate the upper critical field behaviour in FeSe$_{1-x}$S$_x$ system, and found that the upper critical field is higher than that predicted by the Werthamer-Helfand-Hohenberg (WHH) model, whereas its temperature dependence could be fitted within a two-band framework. Finally, a detailed H-T phase diagram is presented.
