Inorganic Chemistry Frontiers , 2 9 , Chemical Communications , 51 , Halides, chalcogenides and pnicnides are for the most part continuous lattice compounds, and, apart from isolated instances that could be regarded more or less as curiosities such as diethyldithiocarbamato-Fe 1II chloride Wickman et al.

These Cu I1 and Cr I1 salts were also excellent realizations of the ferromagnetic exchange arising from orthogonality between orbitals on neighbouring metal centres containing the unpaired electrons, of the kind pointed out by Goodenough and Kanamori for continuous lattice oxides. Organometallic charge transfer salts and one-dimensional ferrimagnetic coordination polymers followed in the s Miller et al. Given the truly enormous number of magnetic solids prepared, characterized and exploited in the last century or so, it is legitimate to ask what new features, either.

There are many. From the point of view of synthesis and processing, the contrast with conventional magnetic materials could not be more stark: substances made at or close to ambient temperature, usually from solution compared with high temperature metallurgical or ceramic processes. A real chance exists to make a soluble magnet! Correlating magnets with other properties, it should be pointed out that all known molecular-based magnetic compounds are insulators, the precise inverse of the situation for continuous lattice materials.

That simple fact has consequences for many of the accompanying properties, of which the most striking and potentially one of the most useful is optical. The molecular-based materials are frequently transparent to infrared and visible light. Combining magnetism with properties only found in the molecular solid state, such as mesomorphism or chirality, would appear to be another potentially fruitful source of novel physics, as is the construction of unusual lattice topologies, such as the Kagom6 lattice, with which to test statistical thermodynamic models of critical behaviour. One apparent drawback of molecular-based magnetic materials, especially in the realm of information storage, is that the large majority are very soft magnets, i.

However, even this limitation is now being breached, as two contributions to this issue demonstrate Kahn, this issue; Kurmoo, this issue. In all, the design, synthesis and study of molecular-based metal-organic and organic magnets has brought supramolecular and coordination chemistry, as well as purely organic synthetic chemistry to bear on a field previously dominated by condensed matter physics. In doing so, it has given new impetus to these fields and provided physics with new objects for study. While technological spin-off is in its infancy, it can confidently be predicted that new applications not replacing, but complementing, existing materials are not far away.

It is to be hoped that the present collection of. Anderson, P.

The transition to ferromagnetic order was realized in with the discovery of a p nitrophenyl nitronyl nitroxide C13H16N crystal. This was the first example of a ferromagnet without metal elements. Its ferromagnetism below the transition temperature of 0. Details of the results of these experiments are described in this paper. Keywords: pnitrophenyl nitronyl nitroxide; p-NPNN; muon spin rotation; pressure effect on ferromagnetism; ferromagnetic to antiferromagnetic transition;.

Solid-state properties of organic compounds have been extensively studied for several decades and it has been revealed that organic solids possess the potential ability to exhibit various interesting properties. The development of organic conductors and superconductors is one such example. In contrast to these advances, the absence of an organic ferromagnet was one of the most conspicuous problems about 10 years ago.

The first explicit theoretical approach for an organic ferromagnet was proposed as early as by McConnell However, no purely organic crystal was found to be a three-dimensional bulk ferromagnet, even after extensive studies on the magnetic properties of organic solids.

About 15 years ago, only a few organic radical crystals were known to exhibit an intermolecular ferromagnetic interaction. One of them was the galvinoxyl radical Mukai et al. We then initiated extensive studies on this compound to search for conditions favouring the ferromagnetic interaction in organic solids. After experimental and theoretical studies over a couple of years, we derived the following conclusion Awaga et al. The requirement for the ferromagnetic intermolecular interaction is twofold, na Published on Dec View Download 8.
