Fast Korringa-Kohn-Rostoker coherent potential approximation and its application to FCC Ni-Fe systems

H Akai - Journal of Physics: Condensed Matter, 1989 - iopscience.iop.org
Abstract A fast KKR CPA method is explained and its convergence properties are examined
numerically. It is shown that a step number of N≃ 300, which determines the number of k …

First-principles investigations of atomic disorder effects on magnetic and structural instabilities in transition-metal alloys

Invar effect, magnetovolume instabilities, and associated low-moment–high-moment (LM …

Calculated magnetic properties of binary alloys between Fe, Co, Ni, and Cu

P James, O Eriksson, B Johansson, IA Abrikosov - Physical Review B, 1999 - APS
We present a detailed theoretical investigation of the magnetic properties of all the binary
alloys between the 3 d elements Fe, Co, Ni, and Cu, in the fcc, bcc, and hcp structures using …

Electronic structure and magnetic properties of dilute Fe alloys with transition-metal impurities

B Drittler, N Stefanou, S Blügel, R Zeller, PH Dederichs - Physical Review B, 1989 - APS
We present ab initio calculations for dilute Fe alloys with 3d and 4d elements. The
calculations are based on local-density approximation of density-functional theory and …

Low relaxation rate in epitaxial vanadium-doped ultrathin iron films

C Scheck, L Cheng, I Barsukov, Z Frait, WE Bailey - Physical review letters, 2007 - APS
The longest relaxation time and sharpest frequency content in ferromagnetic precession is
determined by the intrinsic (Gilbert) relaxation rate G. For many years, pure iron (Fe) has had …

Theoretical aspects of the Invar alloy

IA Abrikosov, O Eriksson, P Söderlind, HL Skriver… - Physical Review B, 1995 - APS
We present first-principles coherent-potential-approximation calculations for the fcc FeNi
alloy. We have found that this system is characterized by a competition between a low-spin …
