Abstract
Diamagnetic susceptibility measurements under high hydrostatic pressure (up to 1.03 GPa) were carried out on a newly discovered Fe-based superconductor LaO1-xFxFeAs (x=0.11). The transition temperature TC, defined as a point at the maximum slope of superconducting transition, was enhanced almost linearly by hydrostatic pressure, yielding a dTC/dP of about 1.2 K GPa−1. Differential diamagnetic susceptibility curves indicate that the underlying superconducting state is complicated. It is suggested that pressure plays an important role on pushing the low TC superconducting phase toward the main (optimal) superconducting phase.Keywords
