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

We carry out Monte Carlo simulations of the uniformly frustrated three dimensional XY model, as a model for vortex line fluctuations in high temperature superconductors in an applied magnetic field. We show, comparing systems of different size, that there are two distinct phase transitions. At a lower Tc⊥, the vortex lattice melts, and coherence is lost in planes perpendicular to the magnetic f...

متن کاملDirect observation of the flux-line vortex glass phase in a type II superconductor.
The order of the vortex state in La1.9Sr0.1CuO4 is probed using muon-spin rotation and small-angle neutron scattering. A transition from a Bragg glass to a vortex glass is observed, where the latter is composed of disordered vortex lines. In the vicinity of the transition the microscopic behavior reflects a delicate interplay of thermally induced and pinning-induced disorder.
متن کاملBasic properties of a vortex in a noncentrosymmetric superconductor
We numerically study the vortex core structure in a noncentrosymmetric superconductor such as CePt3Si without mirror symmetry about the xy plane. A single vortex along the z axis and a mixed singlet-triplet Cooper pairing model are considered. The spatial profiles of the pair potential, local density of states, supercurrent density, and radially-textured magnetic moment density around the vorte...
