Webb11 nov. 2024 · Heusler compounds are commonly used for spintronics applications [1, 4–10]. They can also be used as spin gapless semiconductor or half-metals. The unique interchange splitting of the d-orbitalsresults in half-metallic behavior . In general, the superconducting nature has been found in many Heusler compounds. Webbför 2 dagar sedan · Instead of half Heusler compounds, full and Quaternary Heusler compounds have been explored with theoretical methods and verified results with an experimental approach. J. He and his co-workers [ 30 ] have explored a group of full Heusler compounds such as X 2 AuBi (X = Ca, Sr, Ba) having very low value of lattice …
WebbBoth the full and half-Heusler compounds have been predicted as half-metallic. Recent experimental work has demonstrated that interfacial admixtures of the Heusler alloys with various insulators indeed occur and again reduce spin polarization across such interfaces. Webbthe Heusler and full-Heusler compounds, since several among them have been shown to be half-metals. In this introductory chapter we present a study of the basic electronic and magnetic properties of both Heusler families; the so-called semi-Heusler alloys like NiMnSb and the full-Heusler alloys like Co2 MnGe (usual full-Heuslers),
Webb28 juli 2024 · Heusler and half-Heusler compounds are ternary intermetallic compounds with highly tunable magnetic, topological, multiferroic, and electronic properties.
