The sulfur-substituted FeSe, FeSe 1− x S x, is one of the unique systems that provides an
independent tunability of nematicity, antiferromagnetism, and superconductivity under …

We analyze the relationship between critical current densities (JC) and flux creep rates (S) in
β-FeSe single crystals. This analysis was based on magnetization measurements …
