3D composite metamaterial with magnetic inclusions exhibiting negative stiffness and auxetic behaviour
TL;DR: In this article, a three-dimensional metamaterial composed of structural units consisting of two arrowhead-like elements with magnetic inclusions was investigated, and it was shown that such system has a capability to exhibit negative Poisson's ratio and negative incremental stiffness at the same time.

First-principles investigation of half-metallic ferromagnetism of half-Heusler compounds XYZ
TL;DR: In this paper, the electronic structure and magnetism of half-Heusler compounds were investigated using ab initio density functional theory calculations, and it was shown that the formation energies for these nine half-heusler compound range from −1.32 to −0.12 eV/f.
