Signatures of spectral crossovers in the short- and long-range spectral correlations of a disordered spin-chain with Kramers degeneracy
Debojyoti Kundu, Santosh Kumar, Subhra Sen Gupta
We investigate several distinct spectral crossovers amongst various integrable and quantum-chaotic limits of a 1D disordered quantum spin-1/2 model, by tuning the relative amplitud…
Inelastic neutron scattering investigation of the crystal field excitations of NdCo
F. de Almeida Passos, G. J. Nilsen, C. E. Patrick +6
We present an inelastic neutron scattering study of the crystal electric field levels in the intermetallic ferrimagnets RECo (RE = Nd and Y). In NdCo, measurements at $…
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…
Field-induced canting of magnetic moments in GdCo5 at finite temperature: first-principles calculations and high-field measurements
Christopher E. Patrick, Santosh Kumar, Kathrin Götze +7
We present calculations and experimental measurements of the temperature-dependent magnetization of a single crystal of GdCo in magnetic fields of order 60 T. At zero temperatu…
Calculating the Magnetic Anisotropy of Rare-Earth-Transition-Metal Ferrimagnets
Christopher E. Patrick, Santosh Kumar, Geetha Balakrishnan +4
Magnetocrystalline anisotropy, the microscopic origin of permanent magnetism, is often explained in terms of ferromagnets. However, the best performing permanent magnets based on r…
Rare-earth/transition-metal magnetic interactions in pristine and (Ni,Fe)-doped YCo5 and GdCo5
Christopher E. Patrick, Santosh Kumar, Geetha Balakrishnan +5
We present an investigation into the intrinsic magnetic properties of the compounds YCo5 and GdCo5, members of the RETM5 class of permanent magnets (RE = rare earth, TM = transitio…
