Successive incommensurate spin orderings and excitations in multiferroic SrMnGe2O6
Claire V. Colin, Lei Ding, Eric Ressouche +8
Anisotropic multiferroic properties of SrMnGe2O6 pyroxene single crystals were systematically investigated by means of magnetization, heat capacity, pyroelectric current measuremen…
Loop Currents in Two-leg Ladder Cuprates
Dalila Bounoua, Lucile Mangin-Thro, Jaehong Jeong +4
New phases with broken discrete Ising symmetries are uncovered in quantum materials with strong electronic correlations. The two-leg ladder cuprate \textbf{$Sr_{14-x}Ca_{x}Cu_{24}O…
Onset of a skyrmion phase by chemical substitution in MnGe chiral magnet
E. Altynbaev, N. Martin, A. Heinemann +4
We study the evolution of the magnetic phase diagram of MnFeGe alloys with concentration () by small-angle neutron scattering. We unambiguously…
Increasing the skyrmion stability in CuOSeO by chemical substitution
A. S. Sukhanov, Praveen Vir, A. S. Cameron +7
The cubic chiral helimagnets with the space group represent a group of compounds in which the stable skyrmion-lattice state is experimentally observed. The key parameter th…
Local magnetic anisotropy by polarized neutron powder diffraction: application of magnetically induced preferred crystallite orientation
Iurii Kibalin, Arsen Gukasov
Polarized neutron diffraction allows to determine the local susceptibility tensor on the magnetic site both in single crystals and powders. It is widely used in the studies of sing…
Strong Spin Resonance Mode associated with suppression of soft magnetic ordering in Hole-doped Ba1-xNaxFe2As2
F. Wasser, J. -T. Park, S. Aswartham +6
Spin-resonance modes (SRM) are taken as evidence for magnetically driven pairing in Fe-based superconductors, but their character remains poorly understood. The broadness, the spli…
