Abstract: Abstract Rf penetration depth measurements show (MDT-TTF)2AuI2 to be an ambient pressure superconductor with a Tc ∼4.5 K. The effectof hydrostatic pressure on Tc was found to be −0.92 K/kbar, which suggests that anions longer than AuI2- may puff up the lattice and may yield cation-radical salts of MDT-TTF with even higher superconducting transition temperatures. (MDT-TTF)2AuI2 has a room temperature ESR linewidth of ∼ 100 G, which gradually increases as the temperature is lowered. The structure and properties of (MDT-TTF)2AuI2 bear a clos... (read more)

Topic-specific impact indicators

Popularity: This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network.
Influence: This indicator reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically).
Citation Count: This is an alternative to the "Influence" indicator, which also reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically).
Impulse: This indicator reflects the initial momentum of an article directly after its publication, based on the underlying citation network.
