Prediction of a new efficient permanent magnet SmCoNiFe3
P. Söderlind, A. Landa, I. L. M. Locht +7
We propose a new efficient permanent magnet, SmCoNiFe3, that is a breakthrough development of the well-known SmCo5 prototype. More modern neodymium magnets of the Nd-Fe-B type have…
Magnetic Exchange Interactions in BaMn2As2: A Case Study of the J1-J2-Jc Heisenberg Model
D. C. Johnston, R. J. McQueeney, B. Lake +6
BaMn2As2 is unique among BaT2As2 compounds crystallizing in the body-centered-tetragonal ThCr2Si2 structure, which contain stacked square lattices of 3d transition metal T atoms, s…
Low Energy, Coherent, Stoner-like Excitations in CaFeAs
L. Ke, M. van Schilfgaarde, J. J. Pulikkotil +2
Using linear-response density-functional theory, magnetic excitations in the striped phase of CaFeAs are studied as a function of local moment amplitude. We find a new…
Itinerant magnetic excitations in antiferromagnetic CaFe2As2
S. O. Diallo, V. P. Antropov, T. G. Perring +8
Neutron scattering measurements of the magnetic excitations in single crystals of antiferromagnetic CaFe2As2 reveal steeply dispersive and well-defined spin waves up to an energy o…
Character of magnetic instabilities in CaFe2As2
G. D. Samolyuk, V. P. Antropov
The density functional non-interacting susceptibility has been analyzed in different phases of CaFe2As2 and compared with similar data for pure d-metals. The conditions for the "no…
Anisotropic three-dimensional magnetism in CaFe2As2
R. J. McQueeney, S. O. Diallo, V. P. Antropov +12
Inelastic neutron scattering measurements on the low energy spin waves in CaFe2As2 show that the magnetic exchange interactions in the Fe layers are exceptionally large and similar…
