“…On the other hand, for the LaFeAs(O 1−y F y ) series, the maximum T c emerges at y=0.1 without any development of AFMSFs upon cooling down to T c 14,15,23 , although AFMSFs can be observed in the vicinity of the AFM ordered phase with a lower T c , i.e., in the range of 0.04 < y < 0.08 [24][25][26] . In this context, we emphasize 27,29,30 .…”
