We present flux creep data taken at different temperatures on single crystals of known, ambient pressure, superconductors, CaKFeAs and MgB, taken using the protocol that is common for trapped flux measurements. Using our results, we show that the time dependence of the magnetic moment in HS is remarkably similar to the magnetization relaxation rates observed in established superconductors at ambient pressure, where in the latter cases this can be unambiguously assigned to flux creep.

MgB2 和 CaKFe4As4 中[式略]附近截留磁通量的蠕变

我们展示了在已知环境压力、超导体、CaKFeAs 和 MgB 的单晶上不同温度下获取的通量蠕变数据，这些数据使用捕获通量测量常用的协议获取。利用我们的结果，我们表明，HS 中磁矩的时间依赖性与环境压力下已建立的超导体中观察到的磁化弛豫率非常相似，在后一种情况下，这可以明确地归因于磁通蠕变。
