First-principles studies on electrical resistivity of iron under pressure
Xianwei Sha*, R. E. Cohen
We investigate the temperature and pressure dependences of the electrical resistivity for bcc and hcp Fe using the low-order variational approximation and theoretical transport spe…
Finite-temperature magnetism in bcc Fe under compression
Xianwei Sha*, R. E. Cohen
We investigate the contributions of finite-temperature magnetic fluctuations to the thermodynamic properties of bcc Fe as a function of pressure. First, we apply a tight-binding to…
First-principles thermal equation of state and thermoelasticity of hcp Fe at high pressures
Xianwei Sha, R. E. Cohen
We investigate the equation of state and elastic properties of hcp iron at high pressures and high temperatures using first principles linear response linear-muffin-tin-orbital met…
Non-collinear magnetism in iron at high pressures
R. E. Cohen
Using a first principles based, magnetic tight-binding total energy model, the magnetization energy and moments are computed for various ordered spin configurations in the high pre…
