Physical Property Measurements on Ce<sub>2</sub>Ge<sub>2</sub>Mg
ORAL
Abstract
Ce2Ge2Mg is a member of the R2T2X family of materials (R= rare earth, T=transition metal, X=main group) which crystalize in a layered, tetragonal structure with the magnetic R-ions in individual layers forming a Shastry-Sutherland lattice, with the remaining ions interstitial [1,2]. Ce2Ge2Mg is of particular interest due to the magnetic f-electrons being well below the fermi level, enabling the study of localized magnetic states in a metallic background.
Structural and physical properties of the compound have previously been reported, which indicate an antiferromagnetic phase transition at a Néel Temperature of 9.3K [1,3]. In this talk we will discuss new transport measurements done on single crystals of Ce2Ge2Mg synthesized via the flux method at the University of Kentucky, their implications for magnetic excitations in this material, and the possible presence of topologically protected electronic states.
