Generalized Elliott-Yafet theory of electron spin relaxation in metals: the origin of the anomalous electron spin life-time in MgB2
F. Simon, B. Dora, F. Muranyi +6
The temperature dependence of the electron spin relaxation time in MgB2 is anomalous as it does not follow the temperature dependence of the resistivity above 150 K, it has a maxim…
The electronic structure and the phases of BaVS3
P. Fazekas, K. Penc, K. Radnoczi +8
BaVS3 is a moderately correlated d-electron system with a rich phase diagram. To construct the corresponding minimal electronic model, one has to decide which d-states are occupied…
Slater Transition in the Pyrochlore Cd2Os2O7
D. Mandrus, J. R. Thompson, R. Gaal +7
Cd2Os2O7 crystallizes in the pyrochlore structure and undergoes a metal-insulator transition (MIT) near 226 K. We have characterized the MIT in Cd2Os2O7 using X-ray diffraction, re…
Alkali specific effects in superconducting fullerides: the observation of a high temperature insulating phase in Na_2CsC_60
Natasa Cegar, Ferenc Simon, Slaven Garaj +5
Electron Spin Resonance and optical reflectivity measurements demonstrate a metal-insulator transition in Na_2CsC_60 as the system passes from the low temperature simple cubic to t…
