Magnetic dipole interactions are dominate in quasi one‐dimensional (1D) molecular magnetic materials, in which TbNcPc units (Tb 3+ =terbium(III) ion, Nc 2− =naphthalocyaninato, Pc 2− =phthalocyaninato) adopt a structure similar to TbPc 2 single‐molecule magnets (SMMs). The magnetic properties of the [TbNcPc] 0/+ (neutral 1 Cited by: Over the past fifteen years or so, the study of f-element single-ion magnets (f-SIMs) has gone from being a sub-discipline of molecular magnetism to an established field of research in its own major driving force has been their exceptional promise in applications such as ultra-high-density data storage, spintronics, and quantum information processing (QIP).Cited by: Get this from a library! Spin dynamics: basics of nuclear magnetic resonance. [Malcolm H Levitt] -- NMR spectroscopy is one of the most important and widely used techniques for the identification of compounds. Based on an established course this core text offers a truly modern and updated approach. Influence of the superconducting transition. Serrano and colleagues in Roberta Sessoli’s group at the University of Florence have now found that this interaction also works in the opposite sense: a material undergoing a superconducting transition can influence the spin dynamics of nearby single-molecule magnets. In their experiments, the researchers studied clusters of four iron .

Spin Dynamics: Basics of Nuclear Magnetic Resonance, Second Edition is a comprehensive and modern introduction which focuses on those essential principles and concepts needed for a thorough understanding of the subject, rather than the practical aspects. The quantum theory of nuclear magnets is presented within a strong physical framework, supported by figures.3/5(1). Quantum mechanical effects such as quantum tunneling of magnetization (QTM) and quantum phase interference have been intensively studied in single molecule magnets (SMMs). These materials have also been suggested as candidates for qubits and are promising for molecular spintronics. Understanding decoherence and energy relaxation mechanisms in SMMs is then . In quantum mechanics and particle physics, spin is an intrinsic form of angular momentum carried by elementary particles, composite particles (hadrons), and atomic nuclei. Spin is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum. These quantities are fed into the master equations that govern the spin dynamics. These can be solved numerically, thus providing a full quantitative analysis of the underlying spin-phonon dynamics. The researchers demonstrate their framework on a real single-molecule magnet, namely [(tpa Ph)Fe]-, an S=2 system. Using ORCA, spin Hamiltonian and.

The book is written by experts in the field and is intended as a compilation of critical reviews of new areas rather than a comprehensive text. Sample Chapter(s) Chapter 1: Supramolecular Polymetallic 2D[N x N] Transitionmetal Grids — Approaches to Ordered Molecular Assemblies and Functional Molecular Devices (3, KB). Project: Quantum dynamics of spins in molecular magnets Justin focuses on the study of quantum dynamics of spin in single-molecule magnets at temperatures down to 50mK.

Thus, the spin-network representation is the “non-linear Fock representation for quantum gravity” and this motivates to call the quantum theory we obtain “Quantum Spin Dynamics (QSD)” in analogy with QED or . Magnetic molecules with magnetic bistability have represented the ideal workbench for the investigation of quantum effects in the magnetization dynamics and are now studied at the single molecule level thanks to scanning probe techniques and synchrotron experiments.
