Field-driven magnetostructural transitions in Open
In the spinel compound GeCo$_2$O$_4$, the Co$^{2+}$ pyrochlore sublattice\npresents remarkable magnetic field-induced behaviors that we unveil through\nneutron and X-ray single-crystal diffraction. The N\\'eel ordered magnetic phase\nis en…

Spin anisotropy due to spin-orbit coupling in optimally hole-doped Ba$_{0.67}$K$_{0.33}$Fe$_{2}$As$_{2}$ Open
We use polarized inelastic neutron scattering to study the temperature and energy dependence of spin space anisotropies in the optimally hole-doped iron pnictide Ba$_{0.67}$K$_{0.33}$Fe$_{2}$As$_{2}$ ($T_{\rm c}=38$ K). In the superconduct…

Field-induced spin-density wave beyond hidden order in URu2Si2 Open
URu 2 Si 2 is one of the most enigmatic strongly correlated electron systems and offers a fertile testing ground for new concepts in condensed matter science. In spite of >30 years of intense research, no consensus on the order parameter o…

Helical bunching and symmetry lowering inducing multiferroicity in Fe langasites Open
The chiral Fe-based langasites represent model systems of triangle-based frustrated magnets with a strong potential for multiferroicity. We report neutron scattering measurements for the multichiral Ba3MFe3Si2O14 (M = Nb, Ta) langasites re…

Distinct itinerant spin-density waves and local-moment antiferromagnetism in an intermetallic ErPd2Si2 single crystal Open
Identifying the nature of magnetism, itinerant or localized, remains a major challenge in condensed-matter science. Purely localized moments appear only in magnetic insulators, whereas itinerant moments more or less co-exist with localized…

Longitudinal and Transverse Zeeman Ladders in the Ising-Like Chain Antiferromagnet Open
We explore the spin dynamics emerging from the Néel phase of the chain compound antiferromagnet BaCo(2)V(2)O(8). Our inelastic neutron scattering study reveals unconventional discrete spin excitations, so-called Zeeman ladders, understood …
