Spectroscopic Evidence for Strong Quantum Spin Fluctuations with Itinerant Character in YFe2Ge2
N. Sirica, F. Bondino, S. Nappini +6
We report x-ray absorption and photoemission spectroscopy of the electronic structure in the normal state of metallic YFe2Ge2. The data reveal evidence for large fluctuating spin m…
Nesting, spin-fluctuations, and odd-gap superconductivity in NaxCoO2 yH2O
M. D. Johannes, I. I. Mazin, D. J. Singh +1
We have calculated the one-electron susceptibility of hydrated NaxCoO2 and find strong nesting nearly commensurate with a 2X2 superstructure. The nesting involves about 70% of all…
Electronic Structure of Calcium Hexaboride within the Weighted Density Approximation
Z. Wu, D. J. Singh, R. E. Cohen
We report calculations of the electronic structure of CaB using the weighted density approximation (WDA) to density functional theory. We find a semiconducting band structure w…
Why NiAl is an itinerant ferromagnet but NiGa is not
A. Aguayo, I. I. Mazin, D. J. Singh
NiAl and NiGa are closely related materials on opposite sides of a ferromagnetic quantum critical point. The Stoner factor of Ni is virtually the same in both compounds and…
Measurements of Spin Polarization of Epitaxial SrRuO3 Thin Films
B. Nadgorny, M. S. Osofsky, D. J. Singh +5
We have measured the transport spin-polarization of epitaxial thin films of the conductive ferromagnetic oxide, SrRuO3, using Point Contact Andreev Reflection Spectroscopy (PCAR).…
Thermoelectric power of MgBBe
J. S. Ahn, E. S. Choi, W. Kang +2
We investigated thermoelectric power of MgBBe (, 0.2, 0.3, 0.4, and 0.6). decreases systematically with , suggesting that the hole density incre…
