โœฆ Synopsis


are metallic and exhibit resistivity anomalies below &115 and &80 K, respectively. The origin of these anomalies is explained in terms of their Fermi surfaces. Our study indicates that the resistivity anomalies of these compounds are caused by the partial nesting of their two-dimensional Fermi surfaces and that both K 2 Mo 9 S 11 and Rb 2 Mo 9 S 11 should exhibit a charge density wave phenomenon.

Reinvestigation of the Rb+Mo+S system has led to the discovery of a novel family of reduced molybdenum sul5des with the general formula Rb 2n (Mo 9 S 11 )(Mo 6n S 6nุ‰2 ) (n โ€ซุโ€ฌ 1 to 4) in addition to the previously known compound Rb 2 Mo 6 S 6 . The new rubidium-reduced molybdenum sul5des have been
