Magnetism and spin-fluctuation induced superconductivity in ruthenates
I. I. Mazin, D. J. Singh
This talk summarizes the results published in cond-mat/9703068 (PRL 79,733, 1997) and in cond-mat/9702168 (PR56, 2556, 1997). New results regarding c-dispersion as measered by de H…
First Principles Study of Zn-Sb Thermoelectrics
Seong-Gon Kim, I. I. Mazin, D. J. Singh
We report first principles LDA calculations of the electronic structure and thermoelectric properties of -ZnSb. The material is found to be a low carrier density met…
Nonlocal density functionals and the linear response of the homogeneous electron gas
I. I. Mazin, D. J. Singh
The known and usable truly nonlocal functionals for exchange-correlation energy of the inhomogeneous electron gas are the ADA (average density approximation) and the WDA (weighted…
Where are holes in Y_{1-x}Pr_xBa2Cu3O7 ?
I. I. Mazin, A. I. Liechtenstein
Recent experiments by Mertz et al (Phys. Rev. B55, 9160, 1997) demonstrated that the loss of superconductivity upon Pr doping is associated with the change of the character of the…
Phenomenological interpretations of the ac Hall effect in the normal state of YBa2Cu3O7
Anatoley T. Zheleznyak, Victor M. Yakovenko, H. D. Drew +1
Ac and dc magnetotransport data in the normal state of YBa2Cu3O7 are analyzed within Fermi-liquid and non-Fermi-liquid models. In the Fermi-liquid analysis we use the Fermi surface…
Calculated thermoelectric properties of La-filled skutterudites
D. J. Singh, I. I. Mazin
The thermoelectric properties of La-filled skutterudites are discussed from the point of view of their electronic structures. These are calculated from first principles within the…
Ferromagnetic spin fluctuation induced superconductivity in Sr_2RuO_4
I. I. Mazin, David Singh
We propose a quantitative model for triplet superconductivity in Sr_2RuO_4 based on first principles calculations for the electronic structure and magnetic susceptibility. The supe…
Electronic structure and magnetism in Ru based perovskites
I. I. Mazin, D. J. Singh
The magnetic properties of (Ca,Sr)RuO_3 and Sr_2YRuO_6 are studied within the context of band structure based Stoner theory. LSDA calculations without recourse to strong correlatio…
Effect of magnetic and non-magnetic impurities on highly anisotropic superconductivity
A. A. Golubov, I. I. Mazin
We generalize Abrikosov-Gor'kov solution of the problem of weakly coupled superconductor with impurities on the case of a multiband superconductor with arbitrary interband order pa…
