AC magnetic measurement of LiFeAs at pressures up to 5.2 GPa: The relation between T (c) and the structural parameters

Abstract:

The pressure effects on the 111-type Fe-based superconductor LiFeAs were investigated through AC susceptibility measurements and X-ray diffraction experiments, and revealed a correlation between the superconducting transition temperature (T c) and the As-Fe-As bond angle (α) rather than the height of As from the Fe layers (h As). As the pressure was increased, T c of 17 K at P = 0 GPa decreased down to 10 K at P = 5.2 GPa. According to a previous report from an X-ray diffraction experiment, α...
