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.
They were first described in 1983, as an explanation for the electrical properties of manganese-based Heusler alloys. [60] Although all half-metals are ferromagnetic (or ferrimagnetic), most ferromagnets are not half-metals. Many of the known examples of half-metals are oxides, sulfides, or Heusler alloys. [61]
The periodic table and law are now a central and indispensable part of modern chemistry. The periodic table continues to evolve with the progress of science. In nature, only elements up to atomic number 94 exist; [a] to go further, it was necessary to synthesize new elements in the laboratory.
