Synchrotron Mössbauer spectroscopy (SMS) was performed on an hcp-phase alloy of composition Fe92Ni8 at a pressure of 21 GPa and a temperature of 11 K. Density functional theoretical calculations predict antiferromagnetism in both hcp Fe and hcp Fe-Ni. For hcp Fe, these calculations predict no hyperfine magnetic field, consistent with previous experiments. For hcp Fe-Ni, however, substantial hyp...

In this article, we examine the superconducting properties of lowand high-Tc magnetic superconductors in magnetic fields close to the first penetration field. Attention is paid to the properties that relate to the interactions between antiferromagnetism and superconductivity. It is suggested that several features characterizing the interplay between magnetic and superconducting subsystems in lo...

Results of computer simulations based on ab initio methods are presented for the newly observed magnetism found in carbon-based and non-traditional inorganic materials. These results reinforce our previously proposed explanation about the nature and the origin of this “new type of magnetism” which attributes this to electron correlations effects which develop in the presence of defects and dopi...

Abstract Nuclear beta decays play an important role in uncovering the nature of weak interaction. The magnetism (WM) form factor, b WM , is generally a small correction to decay rate that arises at first order as interference term between dominant Gamow-Teller and magnetic dipole contributions current. This factor still poorly known for nuclei with higher atomic number. We performed careful ana...

The advent of high transverse field muon spin rotation (TF-μSR) has led to recent μSR investigations of the magnetic field response of cuprates above the superconducting transition temperature T(c). Here the results of such experiments on hole-doped cuprates are reviewed. Although these investigations are currently ongoing, it is clear that the effects of high field on the internal magnetic fie...

The magnetism of graphene has remained divergent and controversial due to absence of reliable experimental results. Here we show the intrinsic magnetism of graphene edge states revealed based on unidirectional aligned graphene sheets derived from completely carbonized SiC crystals. It is found that ferromagnetism, antiferromagnetism and diamagnetism along with a probable superconductivity exist...

— The effects of magnetism on high pressure properties of transition metals and transition metal compounds can be quite important. In the case of Fe, magnetism is responsible for stability of the body-centered cubic (bcc) phase at ambient conditions, and the large thermal expansivity in face-centered cubic (fcc) iron, and also has large effects on the equation of state and elasticity of hexagon...
