Fe-site-resolved anisotropy energies in NdFeB for atomistic spin dynamics
Veronica T. C. Lai, Christopher E. Patrick
Nd-Fe-B magnets are the most widely used high performance magnets in the world today, and remain the subject of both experimental and computational research aimed at understanding…
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…
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…
Spin orientation and magnetostriction of TbDyFe from first principles
Christopher E. Patrick, George A. Marchant, Julie B. Staunton
The optimal amount of dysprosium in the highly magnetostrictive rare-earth compounds TbDyFe for room temperature applications has long been known to be =0.73 (Te…
