Metal Fluxes for Crystal Growth

1. Crystal-Chemical Relationships of Correlated Electronic MaterialsJulia Y. ChanDMR-0237664 Metal Fluxes for Crystal Growth • Many useful properties of known extended structure materials suggest that enhanced or new behavior remain to be discovered • Greater structure and electronic degrees of freedom in complicated structures CePdGa6 Ce2PdGa10 Ce2PdGa12 CenMIn3n+2 (n = 1, 2, ∞) CeSb2 LnNiSb2 CeNiSb3 Ln - T - X SnCe3M4Sn12

2. Magnetic and Transport Behavior of LnNi1-xSb2 Magnetoresistance behavior is systematic and scales with the bulk magnetism and correlates to the magnetization.
