Weak antiferromagnetic superexchange interaction in fcc C60Hn

Structural transition and unusually strong antiferromagnetic superexchange coupling in perovskite KAgF3.

High-purity samples of potassium trifluoroargentate(II), KAgF3, have been obtained via a novel synthetic pathway. This compound is found to exhibit an order-disorder phase transition around 230 K. Susceptibility measurements indicate that KAgF3 exhibits strong antiferromagnetic (AFM) coupling reminiscent of that found in copper(II) oxides.

The effect of uniaxial crystal - field anisotropy on magnetic properties of the superexchange antiferromagnetic Ising model

The effect of uniaxial crystal-field anisotropy on magnetic properties of the superexchange antiferromagnetic Ising model The generalized Fisher super-exchange antiferromagnetic model with uniaxial crystal-field anisotropy is exactly investigated using an extended mapping technique. An exact relation between partition function of the studied system and that one of the standard zero-field spin-1...

Interaction Region Lattice for Fcc-ee (tlep)

FCC-ee (TLEP) project is high-luminosity ee collider and is an essential part of the Future Circular Collider (FCC) design study at CERN [1–3]. FCC-ee is being designed to reach center-of-mass energy from 90 to 350 GeV with circumference of 80-100 km to study Higgs boson properties and perform precise measurements at the electroweak scale. It is also an intermediate step towards 100 TeV proton-...
