Origin of Incommensurate Magnetic Order in Rare-Earth Magnetic Weyl Semimetals
Juba Bouaziz, Gustav Bihlmayer, Christopher E. Patrick +2
We investigate rare-earth magnetic Weyl semimetals through first-principles simulations, analyzing the connection between incommensurate magnetic order and the presence of Weyl nod…
A collinear-spin machine learned interatomic potential for FeCrNi alloy
Lakshmi Shenoy, Christopher D. Woodgate, Julie B. Staunton +4
We have developed a new machine learned interatomic potential for the prototypical austenitic steel FeCrNi, using the Gaussian approximation potential (GAP) framework.…
Theory of defect-induced crystal field perturbations in rare earth magnets
Christopher E. Patrick, Yixuan Huang, Laura H. Lewis +1
We present a theory describing the single-ion anisotropy of rare earth (RE) magnets in the presence of point defects. Taking the RE-lean 1:12 magnet class as a prototype, we use fi…
Revisiting Néel 60 years on: the magnetic anisotropy of FeNi (tetrataenite)
Christopher D. Woodgate, Christopher E. Patrick, Laura H. Lewis +1
The magnetocrystalline anisotropy energy of atomically ordered FeNi (the meteoritic mineral tetrataenite) is studied within a first-principles electronic structure…
Interplay between magnetism and short-range order in medium- and high-entropy alloys: CrCoNi, CrFeCoNi, and CrMnFeCoNi
Christopher D. Woodgate, Daniel Hedlund, L. H. Lewis +1
The impact of magnetism on predicted atomic short-range order in three medium- and high-entropy alloys is studied using a first-principles, all-electron, Landau-type linear respons…
Quantification of electronic and magnetoelastic mechanisms of first-order magnetic phase transitions from first principles: application to caloric effects in La(FeSi)
Eduardo Mendive Tapia, Christopher E. Patrick, Tilmann Hickel +2
La(FeSi) and derived quaternary compounds are well-known for their giant, tunable, magneto- and barocaloric responses around a first-order paramagnetic-ferromagn…
Crucial role of Fe in determining the hard magnetic properties of NdFeB
Juba Bouaziz, Christopher E. Patrick, Julie B. Staunton
NdFeB's unsurpassed, hard magnetic properties for a wide range of temperatures result from a combination of a large volume magnetization from Fe and a strong single-ion…
