AbstractSubstitutions in the pyrochlore-type oxide Tl2Mn2O7 have been carried out on both the Mn and the TI site, using high pressure synthesis at 4-6 GPa. We show that a continuous solid solution exists between Tl2Mn2O7, and Tl2Ru2O7, and that the replacement of a fraction of Mn by Ru dramatically changes the transport properties from metallic to semiconducting and induces magnetoresistance (MR) in this system. MRs up to 95% (vs. RO) have been observed. The Tl site, already known to accept In or Sc, can also be substituted by the larger cation Bi3+, which also induces a metal-insulator transition at low substitution level.

Solid solutions of GeTe, AgInTe2 and optionally AgSbTe2 (accessible via high-pressure synthesis or by quenching, depending on the phases’ In content) exhibit remarkable thermoelectric properties that clearly reflect transitions between metastable and stable phases.
