Abstract
We have investigated charge dynamics and electronic structures for single crystals of metallic layered nickelates, R(2-x)Sr(x)NiO(4) (R = Nd, Eu), isostructural to La(2-x)Sr(x)CuO(4). Angle-resolved photoemission spectroscopy on the barely metallic Eu(0.9)Sr(1.1)NiO(4) (R = Eu, x = 1.1) has revealed a large hole surface of x(2) - y(2) character with a high-energy pseudogap of the same symmetry and comparable magnitude with those of underdoped (x < 0.1) cuprates, although the antiferromagnetic interactions are 1 order of magnitude smaller. This finding strongly indicates that the momentum-dependent pseudogap feature in the layered nickelate arises from the real-space charge correlation.
