The new type of molecular magnet, known as a sandwich cluster, is being studied in a joint research project of the U.
The molecular magnets may one day lend a hand in ultrasmall, fast, and energy-efficient computer storage systems.
The potential applications of these materials are diverse and include synthetic skin, molecular magnets
and high-capacity memory storage devices.
Previous research attempts to design and synthesize organic molecular magnets
and high-spin molecules have been unsuccessful.
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).
Density Matrix Equation for a Bathed Small System and its Application to Molecular Magnets
Objective: "A revolution is underway, as molecular magnets
are establishing a fundamental link between spintronics, molecular electronics and quantum computation.
High-abundance proteins, such as albumin, found in blood serum appear to act as molecular magnets
that mop up the fragments, and our work to date demonstrates that these fragments can be identified, measured and analyzed in the context of specific diseases, such as early stage ovarian cancer.
The subject of the use of the spectrometer will be primarily research and development in the field of molecular magnets
and compounds with higher oxidation state of iron.
