Molecule-based magnets are a broad, emerging class of magnetic materials that expand the materials properties typically associated with magnets to include low density, transparency, electrical insulation, and low-temperature fabrication, as well as combine magnetic ordering with other properties such as photoresponsiveness. Essentially all of the common magnetic phenomena associated with conventional transition-metal and rare-earth-based magnets can be found in molecule-based magnets. Although discovered less than two decades ago, magnets with ordering temperatures exceeding room temperature, very high (∼27.0 kOe or 2.16 MA/m) and very low (several Oe or less) coercivities, and substantial remanent and saturation magnetizations have been achieved. In addition, exotic phenomena including photoresponsiveness have been reported. The advent of molecule-based magnets offers new processing opportunities. For example, thin-film magnets can be prepared by means of low-temperature chemical vapor deposition and electrodeposition methods.

Li[TCNE] is a weak ferromagnet whose canting angle, α, as a function of temperature and pressure, α(T) and α(P), have similar but unexpected dependencies that are attributed to a competition between the intra- and interlayer C⋯N interlattice.

The incorporation of the natural amino acid L-proline in the synthesis to vanadium-chromium Prussian blue derivatives results in materials exhibiting magnetic ordering including chiral magnetic centers. Although the amorphous nature of these materials makes difficult to assess the structural features of these proline-containing compounds, magnetic and spectroscopic data confirms their multifunctionality. They exhibit high-temperature magnetic ordering (Tc < 255 K) and a circular dichroic signal, representing the molecule-based chiral magnets with the highest ordering temperatures reported to date. In addition, the presence of chiral L-proline (or D-proline) has additional benefits, including higher redox stability and the appearance of magnetic hysteresis. The latter was not observed in the parent compounds, the series of room temperature molecule-based magnets V[Cr(CN)6]x.

Increasing Temperature

Mossbauer spectra of YC012B6 and NdCo12B6 doped with enriched 57Fe have been obtained at various temperatures between 4�2 K and room temperature. The spectrum of YC012B6 at 4�2 K indicates that the Co sublattice orders in the crystallographic basal plane. NdCo12B6 orders along or close to the crystallographic c-axis at 4�2 K and undergoes a spin-reorientation with increasing temperature until at ~55 K the magnetisation lies in or near the basal plane.
