The anisotropy of magnetic fluctuations propagating along the symmetric directions ⌬ , ⌺, and ⌫ in the ordered phase of uranium dioxide has been studied by applying the spherical neutron-spin polarimetry technique to inelastic neutron scattering. The dependence of fluctuation amplitudes and directions as a function of the quasiparticle wave vector q has been investigated along the main crystallographic directions. The observed behavior is discussed in relation to the spin dynamics of the 3-k transverse magnetic structure. The observed polarization behavior of the spin waves, and in particular the acoustic mode, is shown to be a natural consequence of the transverse 3-k magnetic structure.

“…One consequence of this model is that the two branches should be well separated at ζ = 0.7, but this is not confirmed experimentally. In addition, the crystal-field states predicted by the model have not been observed [12], suggesting that a refinement of the parameters proposed in [8] might be needed.…”

The anisotropy of magnetic fluctuations propagating along the [1 1 0] direction in the ordered phase of uranium antimonide has been studied using polarized inelastic neutron scattering. The observed polarization behavior of the spin waves is a natural consequence of the longitudinal 3-k magnetic structure; together with recent results on the 3-k-transverse uranium dioxide, these findings establish this technique as an important tool to study complex magnetic arrangements. Selected details of the magnon excitation spectra of USb have also been reinvestigated, indicating the need to revise the currently accepted theoretical picture for this material.

“…A second phase transition appears below 142 K with triple-k magnetic order [39]. The magnetic phase diagram tuned by temperature and pressure, magnetic phase transition and spin dynamics have been intensively explored [5,6,11,12,[38][39][40][41][42][43][44][45][46]. Theoretically, the layered Ising model [12] and exchange model [47] have been used to explicate the multi-k antiferromagnetic structures.…”

To unravel the interplay between the strong electronic correlation and itinerant-localized dual nature in atypical f electron systems, we employed the density functional theory in combination with the single-site dynamical mean-field theory to systematically investigate the electronic structures of CeSb and USb. We find that the 4 f states in CeSb are mostly localized which show a weak quasi-particle resonance peak near the Fermi level. Conversely, the 5 f electrons in USb display partially itinerant feature, accompanied by mixed-valence behavior and prominent valence state fluctuations. Particularly, the 4 f electronic correlations in CeSb are distinctly orbital-selective with strikingly renormalized 4 f 5/2 states, according to the low-energy behaviors of 4 f selfenergy functions. It is believed that the strong electronic correlation and fantastic bonding of f states contribute to elucidate the fascinating magnetism. arXiv:1912.10720v1 [cond-mat.str-el]
