Sep 15, 2019 in this work we report the synthesis, structure and magnetic properties of two lanthanoid based coordination polymers (cp) and two dimers.
Jan 15, 2019 in this work the magnetic coupling problem for this dimer is past studies of problematic dft behavior for the chromium dimer were frustrated.
We consider the magnetism of 5% mn doped fibres to be originated from the magnetic moment of mn itself, the charge compensation effect and the in- cident impurity phases. Nevertheless, the pop-in of the ca might have indirectly conflicted with mn somehow, for instance, pinned the mn valence state.
We investigate the magnetic properties of the system cute2o5 by susceptibility and electron spin resonance.
Aug 4, 2015 two recent experiments displaying fermi liquid behavior at low p are dimer models of doped spin liquids have also been studied (49, 55, 56), but all note that the dispersion is not symmetric about the magnetic bril.
Which is required in spin injection where su cient polar-ized spin current is required [27, 28], so it is proposed that tms doped diamond can be used as spin injection charge carriers. In the present study we used the same techniques for magnetic coupling as used in [26].
Magnetic excitations associated with mn3+ dimers give evidence for two different performed with use of a quantum design magnetic properties measurement.
Spin dimer compounds are based on pairs of spins with antiferromagnetic exchange. At low fields the ground state is a product of singlets, with excited triplet states at higher energies. Application of a magnetic field closes the spin gap between the excited triplet state and singlet state.

Magnetic behavior of a spin-1 heisenberg dimer is analysed in dependence on both uniaxial single-ion anisotropy and xxz exchange anisotropy in a zero- as well as non-zero longitudinal magnetic field. A complete set of eigenfunctions and eigenvalues of the total hamiltonian is presented together with an exact analytical expression for the gibbs free energy, longitudinal magnetization.
Nov 7, 2016 this work explores the magnetic properties of electron-doped sr3ir2o7 via resonant x-ray scattering measurements and static spin susceptibility.
The helium dimer is a van der waals molecule with formula he 2 consisting of two helium atoms. This chemical is the largest diatomic molecule —a molecule consisting of two atoms bonded together. The bond that holds this dimer together is so weak that it will break if the molecule rotates, or vibrates too much.
A bar magnet is called a dipole because it has two poles (commonly labeled an ideal dipole, you can see if your magnet is very nearly a dipole in its behavior.
Doping a semiconductor in a good crystal introduces allowed energy states within the band gap, but very close to the energy band that corresponds to the dopant type. In other words, electron donor impurities create states near the conduction band while electron acceptor impurities create states near the valence band.
Quantum spin liquids are exotic mott insulators that carry extraordinary spin excitations. Therefore, when doped, they are expected to afford metallic states with unconventional magnetic.
The doped quantum heisenberg antiferromagnets are extremely alluring for their interesting magnetic properties and inherent itinerant character. Even the magnetic behaviors of the one-dimensional and two-dimensional antiferromagnets are quite distinct which is in contrast to the age old idea of the theoreticians and experimentalists.
The magnetic stability of fe dimer doped azsinrs can be understood from the electronic band structures and the interaction between the magnetic moments. It was mentioned earlier that the analysis of pdos shows two peaks for minority spins at the valence and conduction bands, which are due to the fe-3d orbital, and signifies its magnetic stability.

However, inter-dimer interaction is found to be stronger in the mn doped samples. The underlying magnetic behaviour of these doped samples is presumably related to the effect of broken dimers due to random substitutions.
The underlying magnetic behaviour of these doped samples is presumably related to the effect of broken dimers due to random substitutions. We report the effect of substitution of cr by v and mn in the spin- 1/2 1 2 dimer compound srsub3/subcrsub2/subosub8/sub.
In condensed matter physics, the quantum dimer magnet state is one in which quantum spins in a magnetic structure entangle to form a singlet state.
