We report low-temperature รฐTX40 mKร magnetization measurements on YbRh 2 Si 2 and YbIr 2 Si 2 at magnetic fields up to 11.5 T and under hydrostatic pressure Pp1:35 GPa. The magnetization slope in YbRh 2 Si 2 changes drastically under pressure, while that of YbIr 2 Si 2 is less sensitive to pressure.
The three title compounds are found to form stable negatively charged states. Si2H2 exhibits two anion states (2A s and 2Bs) corresponding to adiabatic electron affinities (EAs) of 1.76 and 1.23 eV. Si2H3 has two stable anion states ( tA and 3A) associated with EAs of 2.20 and I. 17 eV. Disilene sho
