Characterization of molecular magnets using EPR

Abstract

Molecules involving tetracyanoethylene (TCNE) and transition or rare earth compounds have been found to exhibit magnetic properties at low temperature. One compound, however, with V and TCNE has been found to have an ordering temperature above 300 K. A compound with Fe and TCNE has shown to exhibit 32% more magnetization in molecules than iron metal. Molecular magnet compounds can be dissolved in a solvent, added to a matrix such as a polymer, and do not require metallurgical processing. Since magnetism is a very basic science, application possibilities for molecular magnets are broad, stretching from nanotechnology to high density information storage.
