The magneto-transport properties are systematically measured under c-direction fields up to 33 T for a series of single-crystal films of intercalated iron-selenide superconductor (Li,Fe)OHFeSe. The film samples with varying degree of disorder are grown hydrothermally. We observe a magnetic-field-enhanced shoulder-like feature in the mixed state of the high-T _c (Li,Fe)OHFeSe films with weak disorder, while the feature fades away in the films with enhanced disorder. The irreversibility field is significantly suppressed to lower temperatures with the appearance of the shoulder feature. Based on the experiment and model analysis, we establish a new vortex-phase diagram for the weakly-disordered high-T _c (Li,Fe)OHFeSe, which features an emergent dissipative vortex phase intermediate between the common vortex glass and liquid phases. The reason for the emergence of this intermediate vortex state is further discussed based on related experiments and models.

在高温 c 超导体 (Li,Fe)OHFeSe 中发现的一种对紊乱敏感的涡流相

系统地测量磁传输特性C- 一系列插层硒化铁超导体 (Li,Fe)OHFeSe 单晶薄膜的方向场高达 33 T。水热生长具有不同程度无序的薄膜样品。我们在高-混合状态下观察到磁场增强的肩状特征吨 _c (Li,Fe)OHFeSe 薄膜具有较弱的无序性，而特征在具有增强无序性的薄膜中逐渐消失。随着肩部特征的出现，不可逆场被显着抑制以降低温度。基于实验和模型分析，我们建立了一个新的弱无序高-涡旋相图吨 _c (Li,Fe)OHFeSe，具有介于普通涡旋玻璃和液相之间的突现耗散涡旋相。基于相关实验和模型进一步讨论了出现这种中间涡流状态的原因。
