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…
Temperature-dependent magnetocrystalline anisotropy of rare earth/transition metal permanent magnets from first principles: The light RCo (R=Y, La-Gd) intermetallics
Christopher E. Patrick, Julie B. Staunton
Computational design of more efficient rare earth/transition metal (RE-TM) permanent magnets requires accurately calculating the magnetocrystalline anisotropy (MCA) at finite tempe…
Accurate ground state- and quasiparticle energies: beyond the RPA and GW methods with adiabatic exchange-correlation kernels
Thomas Olsen, Christopher E. Patrick, Jefferson E. Bates +2
We review the theory and application of adiabatic exchange-correlation (xc-) kernels for ab initio calculations of ground state energies and quasiparticle excitations within the fr…
Crystal field coefficients for yttrium analogues of rare-earth/transition-metal magnets using density-functional theory in the projector-augmented wave formalism
Christopher E. Patrick, Julie B. Staunton
We present a method of calculating crystal field coefficients of rare-earth/transition-metal (RE-TM) magnets within density-functional theory (DFT). The principal idea of the metho…
Structural and magnetic properties of GdCoNi
Amy L. Tedstone, Christopher E. Patrick, Santosh Kumar +4
GdCo may be considered as two sublattices - one of Gd and one of Co - whose magnetizations are in antiparallel alignment, forming a ferrimagnet. Substitution of nickel in the c…
First-principles calculations of the magnetocrystalline anisotropy of the prototype 2:17 cell boundary phase Y(CoFeCu)
Christopher E. Patrick, Munehisa Matsumoto, Julie B. Staunton
We present a computational study of the compound Y(CoFeCu) for 0 . This compound was chosen as a prototype for investigating the cell bound…
