The Effect of Geometry on Electronic Properties of Transition Metal Compounds

Abstract

The effect of geometry, particularly, geometric frustration on electronic properties of itinerant electron magnets are discussed. As an example, the competition between intra- and inter-dimer interaction, and the characteristic lattice dynamics in Mo₃Sb₇ are briefly reviewed. A new possible and promising candidate of the metallic frustrated lattice, the stella quadrangula lattice, found in compounds with the η-carbide type structure, etc., is introduced.
