Copper Keplerates: High-Symmetry Magnetic Molecules

Abstract

Keplerates are molecules that contain metal polyhedra that describe both Platonic and Archimedean solids; new copper keplerates are reported, with physical studies indicating that even where very high molecular symmetry is found, the low-temperature physics does not necessarily reflect this symmetry.

Keywords: copper; cuboctahedron; frustration; keplerates; molecular symmetry.
