Solution of the Schrödinger Equation in Periodic Lattices with an Application to Metallic Lithium
Walter Kohn,Norman Rostoker +1 more
TL;DR: In this article, the problem of solving the Schrodinger equation in a periodic lattice is studied from the point of view of the variation-iteration method, which leads to a very compact scheme if the potential $V(r)$ is spherically symmetrical within the inscribed spheres of the atomic polyhedra and constant in the space between them.

Magnetic order and phase transformation in Ni2MnGa
TL;DR: In this article, a martensitic phase transition to a complex tetragonal structure occurs on cooling below 202 K. Reasons for the structural transformation are discussed, and details of the low temperature crystallographic superlattice and magnetic structure are determined.

Formation and coupling of magnetic moments in Heusler alloys
TL;DR: In this article, the microscopic mechanisms responsible for both the formation and coupling of magnetic moments in Heusler alloys were identified, and it was shown that the $X$ atoms (e.g., Cu, Pd) serve primarily to determine the lattice constant, while the $Y$ atoms mediate the interaction between the $\mathrm{Mn}d$ states.
