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…
Discovery and implications of hidden atomic-scale structure in a metallic meteorite
András Kovács, Laura H. Lewis, Dhanalaksmi Palanisamy +7
Iron and its alloys have made modern civilisation possible, with metallic meteorites providing one of the human's earliest sources of usable iron as well as providing a window into…
Superconducting and Antiferromagnetic Properties of Dual-Phase VGa
Michelle E. Jamer, Brandon Wilfong, Vasiliy D. Buchelnikov +11
The binary compound VGa can exhibit two near-equilibrium phases, consisting of the A15 structure that is superconducting, and the Heusler D0 structure that is semiconductin…
Structural and electronic properties of the spin-filter material CrVTiAl with disorder
Gregory M. Stephen, Gianina Buda, Michelle E. Jamer +7
The effects of chemical disorder on the transport properties of the spin-filter material CrVTiAl are investigated experimentally and theoretically. Synchrotron X-ray diffraction ex…
Low-moment ferrimagnetic phase of the Heusler compound Cr2CoAl
Michelle E. Jamer, Luke G. Marshall, George E. Sterbinsky +2
Synthesizing half-metallic fully-compensated ferrimagnets that form in the inverse Heusler phase could lead to superior spintronic devices. These materials would have high spin pol…
