Study of nematicity in iron pnictide BaFe<sub>2</sub>(As<sub>1-x</sub>P<sub>x</sub>)<sub>2</sub> with micro-ARPES

ORAL

Abstract

Iron pnictides posses a rich phase diagram. In particular, the nematic phase has drawn much attention for its proximity to superconductivity. Recently, nematicity has been observed above the tetragonal-to-orthorhombic structural transition temperature. Such observations generated interest in nematic fluctuations and rasied questions about the origin of the nematic phase of iron based superconductors. With small beam spot micro-Angle-Resolved Photo Emission Spectroscopy (µARPES) technique, spatial variations in dispersion and Fermiology in the nematic fluctuation regime was studied. providing new insights about the nature of nematicity.
