Ferromagnetism in one-dimensional monatomic metal chains.
Pietro Gambardella,A. Dallmeyer,Kalobaran Maiti,M. C. Malagoli,Wolfgang Eberhardt,Klaus Kern,Carlo Carbone,Carlo Carbone +7 more
TL;DR: Evidence is found that the monatomic chains consist of thermally fluctuating segments of ferromagnetically coupled atoms which, below a threshold temperature, evolve into a ferromagnetic long-range-ordered state owing to the presence of anisotropy barriers.

Magnetism in ultrathin film structures
TL;DR: In this article, the results of recent experimental and theoretical studies of well characterized epitaxial structures based on Fe, Co and Ni to illustrate how intrinsic fundamental properties such as the magnetic exchange interactions, magnetic moment and magnetic anisotropies change markedly in ultrathin films as compared with their bulk counterparts, and to emphasize the role of atomic scale structure, strain and crystallinity in determining the magnetic properties.

Giant magnetic anisotropy in tetragonal FeCo alloys.
TL;DR: The discovered alloy has a saturation magnetization that is about 50% larger than that of FePt--a compound that has received considerable attention lately-with a uniaxial MAE that can easily be tailored reaching a maximum value that is 50% smaller than thatof FePT.

Electronic structure theory of surface, interface and thin-film magnetism
Arthur J Freeman,Ru quian Wu +1 more
TL;DR: In this paper, local spin density functional (LSDF) ab initio electronic structure calculations played a key role in the development of this exciting field by not only providing a clearer understanding of the experimental observations but also predicting new systems with desired properties.

The remarkable difference between surface and step atoms in the magnetic anisotropy of two-dimensional nanostructures
Stefano Rusponi,Tristan Cren,Nicolas Weiss,M. Epple,Philipp Buluschek,L. Claude,Harald Brune +6 more
TL;DR: A method enabling the identification of the remarkably different contributions of surface and perimeter atoms to the magnetic anisotropy energy of two-dimensional nanostructures is introduced, using the generally nonlinear relationship between perimeter length and surface area.

Self-Consistent Equations Including Exchange and Correlation Effects
Walter Kohn,L. J. Sham +1 more
TL;DR: In this paper, the Hartree and Hartree-Fock equations are applied to a uniform electron gas, where the exchange and correlation portions of the chemical potential of the gas are used as additional effective potentials.

Inhomogeneous Electron Gas
P. C. Hohenberg,Walter Kohn +1 more
TL;DR: In this article, the ground state of an interacting electron gas in an external potential was investigated and it was proved that there exists a universal functional of the density, called F[n(mathrm{r})], independent of the potential of the electron gas.
