Phase diagrams sketches demonstrating how Double and Triple Half-Heusler compositions are different from traditional alloy compositions. [7]Although traditionally thought to form at compositions XYZ and X 2 YZ, studies published after 2015 have discovered and reliably predicted Heusler compounds with atypical compositions such as XY 0.8 Z and X 1.5 YZ.

Half-metals were first described in 1983, as an explanation for the electrical properties of manganese-based Heusler alloys. [3] Some notable half-metals are chromium(IV) oxide, magnetite, and lanthanum strontium manganite (LSMO), [1] as well as chromium arsenide. Half-metals have attracted some interest for their potential use in spintronics.
Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3 ; it is usually shown at the foot of the table to save horizontal space.
