论文摘要
对于一系列插入的铁 - 羟基超导体（LI，FE）OHFESE的单晶膜，在高达33 t的C方向上系统测量了磁铁转运性能。具有变化程度的薄膜样品是水热种植的。我们观察到具有弱疾病的高-TC（Li，Fe）Ohfese膜的混合状态中的磁场增强肩状特征，而该功能在具有增强障碍的电影中逐渐消失。肩部特征的出现，不可逆性场被显着抑制降低温度。基于实验和模型分析，我们为弱小的高-TC（LI，FE）OHFESE建立了一个新的涡流相图，该图具有出现的爆发性涡旋相中的中间位置。根据相关的实验和模型，进一步讨论了这种中间涡流状态的出现的原因。
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-Tc (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-Tc (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.
