Strong anisotropy and magnetostriction in the two-dimensional Stoner ferromagnetFe3GeTe2
Open accessAbstract
Computationally characterizing magnetic properies of novel two-dimensional (2D) materials serves as an important first step of exploring possible applications. Using density-functional theory, we show that single-layer ${\mathrm{Fe}}_{3}{\mathrm{GeTe}}_{2}$ is a potential 2D material with sufficiently low formation energy to be synthesized by mechanical exfoliation from the bulk phase with a van der Waals layered structure. In addition, we calculated the phonon dispersion demonstrating that single-layer ${\mathrm{Fe}}_{3}{\mathrm{GeTe}}_{2}$ is dynamically stable. Furthermore, we find that similar to the bulk phase, 2D ${\mathrm{Fe}}_{3}{\mathrm{GeTe}}_{2}$ exhibits a magnetic moment that originates from a Stoner instability. In contrast to other 2D materials, we find that single-layer ${\mathrm{Fe}}_{3}{\mathrm{GeTe}}_{2}$ exhibits a significant uniaxial magnetocrystalline anisotropy energy of $920\ensuremath{\mu}\mathrm{eV}$ per Fe atom originating from spin-orbit coupling. Finally, we show that applying biaxial tensile strains enhances the anisotropy energy, which reveals strong magnetostriction in single-layer ${\mathrm{Fe}}_{3}{\mathrm{GeTe}}_{2}$ with a sizable magneostrictive coefficient. Our results indicate that single-layer ${\mathrm{Fe}}_{3}{\mathrm{GeTe}}_{2}$ is potentially useful for magnetic storage applications.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
