SPECIAL PROGRAM ON CONDENSED SYSTEMS OF LOW DIMENSIONALITY

PREFACE
The research of unitary concepts in solid state and molecular chemistry is of current interest
for both chemist and physicist communities. It is clear that due to their relative simplicity, low
dimensional materials have attracted most of the attention. Thus, many non-trivial problems were
solved in chain systems, giving some insight into the behavior of real systems which would
otherwise be untractable.
The NATO Advanced Research Workshop on "Organic and Inorganic Low-Dimensional
Crystalline Materials" was organized to review the most striking electronic properties exhibited by
organic and inorganic sytems whose space dimensionality ranges from zero (Od) to one (1d), and to
discuss related scientific and technological potentials. The initial objectives of this Workshop were,
respectively:
i) To research unitary concepts in solid state physics, in particular for one dimensional compounds,
ii) To reinforce, through a close coupling between theory and experiment, the interplay between
organic and inorganic chemistry, on the one hand, and solid state physics on the other,
iii) To get a salient understanding of new low-dimensional materials showing "exotic" physical
properties, in conjunction with structural features.
To reach these goals, the meeting was organized in three different steps as reported in the
table of contents. The first sessions were devoted to plenary lectures on the different classes of low
dimensional materials presenting either a mixed-valence or a magnetic character. Topics relative to
organic as well as inorganic materials were rewieved; this is rather unusual in standard conferences,
since researches on conducting and magnetic compounds are traditionally segregated. These
presentations were followed by a series of review papers on the physical properties, mainly on
magnetic aspects (phase transitions, linear and nonlinear excitations, Haldane conjecture, .. etc). One
special session was organized on the new superconducting materials, the organic ones as well as
the new ternary oxides which present superconductivity above the boiling point of liquid nitrogen. In
addition to the first series of review papers, several lectures were given on special topics in
connection with the main subject. These lectures were devoted to the problem of charge transfer in
biological systems, studies on large metallic clusters, which are regarded as "zero-dimensional
systems", and potential applications of mixed valence compounds, including equally organized
monomolecular layer systems (Langmuir-Blodgett films). The purpose of these special sessions was
both to increase the convergence between researches whose goals are different, and to get further
information before the round table discussions.
vii
For a complementary level of information, each participant presented one poster relevant to
these topics; the new results on magnetic chains as well as on conducting materials are included as
short contributions in this book.
The last part was devoted to the round tables on prospects and developments. The
proposed subjects (new conducting systems, new magnetic compounds, ferromagnets, competition
between magnetism - superconductivity and charge density waves, potential technology directions)
were presented by the group leaders, then discussed in small groups of abo!Jl ten persons.
Schemes for designing new types of materials were reported. Summaries of these discussions are
given in the last part of this volume.
The concluding remart<s .were given by Prof. V.J. Emery, who emphasized the interest in
using large equipments, such as different neutron reactors or synchrotron sources, for analyzing
crystal structures (long-range order but also local organization, structural phase transitions, .. etc). An
outstanding example of new unexpected and very stimulating findings is the discovery of the new
"high T c" superconductors.
We wish to mention that this NATO wort<shop was prepared and organized thanks to the
positive contribution of the organizing committee (D. Beltran (Spain), R. Cariin (USA), LJ. de Jongh
(Netheriands), and J. Rouxel (France)), and the enthusiasm during the preparation of study-group
reports of the leaders (A. Barraud (France), D. Brom (Netheriands), R. Cariin (USA), H.J. Keller
(Germany) and F. Palacio (Spain)).
Finally, we wish to thank the panel on "Condensed Systems of Low Dimensionality" of
NATO's Scientific Affairs Division for the financial and administrative support which made this
workshop possible.
