High-T C fully compensated ferrimagnetic semiconductors as spin-filter materials: the case of CrVXAl (X = Ti, Zr, Hf) Heusler compounds.
TL;DR: It is shown that p-d hybridization leads to the formation of a fully compensated ferrimagnetic semiconducting state with moderate exchange splitting and the combination of very high TC values with a zero total net magnetization makes CrVXAl compounds promising materials for spintronics applications.

Philipp Dürrenfeld,F. Gerhard,Jonathan Chico,Randy K. Dumas,Mojtaba Ranjbar,Anders Bergman,Lars Bergqvist,Lars Bergqvist,Anna Delin,Anna Delin,Anna Delin,Charles Gould,Laurens W. Molenkamp,Johan Åkerman,Johan Åkerman +14 more
TL;DR: The half-metallic half-Heusler alloy NiMnSb is a promising candidate for applications in spintronic devices due to its low magnetic damping and its rich anisotropies as mentioned in this paper.

Shubnikov-de Haas oscillations, weak antilocalization effect and large linear magnetoresistance in the putative topological superconductor LuPdBi
TL;DR: Electronic transport and magnetic properties of single crystals of semimetallic half-Heusler phase LuPdBi reveal charge carriers with effective mass of 0.06 me and a Berry phase very close to π, expected for Dirac-fermion surface states, thus corroborating topological nature of the material.

Generalized Gradient Approximation Made Simple
TL;DR: A simple derivation of a simple GGA is presented, in which all parameters (other than those in LSD) are fundamental constants, and only general features of the detailed construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked.

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.

TL;DR: A way is found to visualize and understand the nonlocality of exchange and correlation, its origins, and its physical effects as well as significant interconfigurational and interterm errors remain.

Generalized Gradient Approximation Made Simple [Phys. Rev. Lett. 77, 3865 (1996)]
TL;DR: For the molecules Be2, F2, and P2 of Table I, the unrestricted Hartree-Fock solution breaks the singlet spin symmetry, even though the density functional solutions do not.

Giant magnetoresistance of (001)Fe/(001)Cr magnetic superlattices.
Mario Norberto Baibich,J. M. Broto,Albert Fert,F. Nguyen Van Dau,Frédéric Petroff,P. Etienne,G. Creuzet,A. Friederich,Jean Chazelas +8 more
TL;DR: This work ascribes this giant magnetoresistance of (001)Fe/(001)Cr superlattices prepared by molecularbeam epitaxy to spin-dependent transmission of the conduction electrons between Fe layers through Cr layers.
