Structural analysis and transport properties of [010]-tilt grain boundaries in Fe(Se,Te)
Kazumasa Iida, Yoshihiro Yamauchi, Takafumi Hatano +10
Understanding the nature of grain boundaries is a prerequisite for fabricating high-performance superconducting bulks and wires. For iron-based superconductors [e.g. Ba(Fe,Co)A…
