Developments towards an understanding of the nature of conductance at the interface between two different metallic layers – ferromagnetic and non magnetic – as well as the discovery of giant magnetoresistance have stirred attention from both the scientific ...
We show that double-resonance spectra recorded during the simultaneous absorption of x-ray and microwave (MW) photons are a fingerprint of the perturbed electronic configuration of atomic species driven to ferromagnetic resonance. X-ray absorption measurem ...
The phenomenon of magnetism is one of the key components of today's technological progress. Magnetic interactions and magnetic materials are essential for the scientific disciplines of physics, chemistry and biology, making this subject truly multidiscipli ...
The molecular dynamics of a series of organometallic complexes covalently bound to amorphous silica surfaces is determined experimentally using solid-state nuclear magnetic resonance (NMR) spectroscopy and density functional theory calculations (DFT). The ...
A general protocol for the structural characterization of paramagnetic molecular solids using solid-state NMR is provided and illustrated by the characterization of a high-spin FeII catalyst precursor. We show how good NMR performance can be obtained on a ...
We performed an ab initio mol. dynamics simulation of the paramagnetic transition metal ion Cr3+ in aq. soln. Isotropic hyperfine coupling consts. between the electron spin of the chromium ion and nuclear spins of all water mols. have been detd. for instan ...
Nuclear magnetic relaxation in the presence of paramagnetic centres has gained increasing interest in recent years partly due to its importance for contrast agents in magnetic resonance imaging. Rational design of new more efficient agents is possible as a ...
The authors present a method to calc. NMR chem. shielding tensors in condensed phases by a hybrid quantum mech./mol. mech. (QM/MM) approach. The authors propose a modification of the conventional QM/MM technique, adding a general repulsive potential to the ...
Multiple experiments (17O NMR, 1H NMR, and EPR) have been performed in the past to understand the microscopic parameters that control the magnetic relaxation rate enhancement induced by paramagnetic molecules on neighboring water protons, the so-called rel ...
he structure and dynamics of the surrounding water were studied through molecular dynamics (MD) simulations for several GdIII polyaminocarboxylate and polyaminophosphonate complexes in aqueous solution. The radial distribution functions (rdf) show that a f ...
