Neutron scattering from local magnetoelectric multipoles: a combined theoretical, computational, and experimental perspective
Andrea Urru, Jian-Rui Soh, Navid Qureshi +4
We address magnetic neutron scattering in the presence of local non-centrosymmetric asymmetries of the magnetization density. Such inversion-symmetry breaking, combined with the ab…
Fast broadband cluster spin-glass dynamics in PbFeNbO
C. Stock, B. Roessli, P. M. Gehring +11
PbFeNbO (PFN) is a relaxor ferroelectric (T 400 K) consisting of disordered magnetic Fe (S=, L0) ions resulting in a l…
Dipolar spin-waves and tunable band gap at the Dirac points in the 2D magnet ErBr3
C. Wessler, B. Roessli, K. W. Krämer +4
Topological magnon insulators constitute a growing field of research for their potential use as information carriers without heat dissipation. We report an experimental and theoret…
Spin Density Wave versus Fractional Magnetization Plateau in a Triangular Antiferromagnet
L. Facheris, K. Yu. Povarov, S. D. Nabi +7
We report an excellent realization of the highly non-classical incommensurate spin-density wave (SDW) state in the quantum frustrated antiferromagnetic insulator CsCoBr. In…
Mesoscopic tunneling in strontium titanate
Benoît Fauqué, Philippe Bourges, Alaska Subedi +6
Spatial correlation between atoms can generate a depletion in the energy dispersion of acoustic phonons. Two well known examples are rotons in superfluid helium and the Kohn anomal…
Observation of plaquette fluctuations in the spin-1/2 honeycomb lattice
C. Wessler, B. Roessli, K. W. Krämer +6
Quantum spin liquids are materials that feature quantum entangled spin correlations and avoid magnetic long-range order at T = 0 K. Particularly interesting are two-dimensional hon…
