Giant magnetocaloric effect in Co2FeAl Heusler alloy nanoparticles.
TL;DR: In this article, a giant magnetocaloric effect across the ferromagnetic (FM) to paramagnetic (PM) phase transition was observed in chemically synthesized Co2FeAl Heusler alloy nanoparticles with a mean diameter of 16 nm.
Journal ArticleDOI
The chemical bond as an emergent phenomenon
TL;DR: In this article, the symmetry breaking is controlled by density and electronegativity variation, and it is shown that the bond order changes with bond deformation but in a step-like fashion, regions of near constancy separated by electronic localization transitions.
Journal ArticleDOI
A new class of topological insulators from I-III-IV half-Heusler compounds with strong band inversion strength
TL;DR: In this article, the band topology of a new half-Heusler family with composition of I(A)-III-A)-IV(A) was investigated by first principle calculations.

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.

Atoms, molecules, solids, and surfaces: Applications of the generalized gradient approximation for exchange and correlation.
John P. Perdew,J. A. Chevary,S. H. Vosko,Koblar A. Jackson,Mark R. Pederson,David J. Singh,Carlos Fiolhais +6 more
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.
