The new type of molecular magnet
, known as a sandwich cluster, is being studied in a joint research project of the U.S.
Previous research attempts to design and synthesize organic molecular magnets
and high-spin molecules have been unsuccessful.
Magnetic MOFs and molecular magnets
reported with their designs, synthetic approaches, structures, and physical properties [25-33] are both branches of coordination chemistry where metals are bound in a solid by coordination bonds to organic linkers.
This study aimed at developing new molecular magnets
having magnetic properties that can be controlled by light, electrochemical reaction, and chemical stimuli.
Following the introduction, chapters discuss synthesis of nanoparticulate magnetic materials; preparation and properties of magnetic metallopolymer nanocomposites; magnetic nanocomposites based on the metal containing nanoparticles inside the polyethylene matrix; preparation, structure, and properties of organized ensembles of magnetic nanoparticles; effects of size, shape, and interactions on the magnetism of nanoparticles; electron magnetic resonance of nanoparticles; micromagnetics of small ferromagnetic particles; high-spin polynuclear carboxylate complexes and molecular magnets
with VII and VIII group 3d-metals; and biomedical applications of magnetic nanoparticles.
In contrast to previously reported molecular magnets
, their compounds have an unusual 2:1 metal to ligand ratio and also are comparably stable at ambient conditions.
Other types of systems that have been investigated with magnetic diffraction include heavy fermion systems (8-13), ruthenates (14-15) and cobalates (16-17), amorphous (18) and nanocrystalline (19-21) systems, frustrated magnets (22-24), molecular magnets
, (25-26) and colossal magnetoresistive oxides (27-33).
