Rearrangement of orbitals in KAgF3 due to Kugel-Khomskii mechanism: a Neutron diffraction and Density Functional Theory study
Kacper Koteras, Sebastian Biesenkamp, Paolo Barone +6
The crystal structure of KAgF3 was studied by powder neutron diffraction. KAgF3 exhibits at all temperatures an orthorhombic symmetry in space group Pnma that allows for several di…
Multiferroic domain relaxation in (NH4)2[FeCl5(H2O)]
Sebastian Biesenkamp, Karin Schmalzl, Petra Becker +2
The molecular compound (NH4)2[FeCl5(H2O)] is a type-II multiferroic material, in which incommensurate cycloidal order directly induces ferroelectric polarization. The multiferroic…
Spin-wave dispersion and magnon chirality in multiferroic TbMnO3
S. Holbein, P. Steffens, S. Biesenkamp +4
Inelastic neutron scattering experiments combining time-of-flight and polarized techniques yield a comprehensive picture of the magnon dispersion in multiferroic TbMnO3 including t…
Low temperature magnetism of KAgF3
John M. Wilkinson, Stephen J. Blundell, Sebastian Biesenkamp +7
KAgF is a quasi one-dimensional quantum antiferromagnet hosting a series of intriguing structural and magnetic transitions. Here we use powder neutron diffraction, SR spectr…
Chiral Order and Multiferroic Domain Relaxation in NaFeGeO
S. Biesenkamp, D. Gorkov, W. Schmidt +5
The magnetic structure and the multiferroic relaxation dynamics of NaFeGeO were studied by neutron scattering on single crystals partially utilizing polarization analysis.…
Single-crystal investigations on the multiferroic material LiFe(WO)
S. Biesenkamp, D. Gorkov, D. Brüning +9
The crystal and magnetic structure of multiferroic LiFe(WO) were investigated by temperature and magnetic-field dependent specific heat, susceptibility and neutron diffract…
Structural dimerization in the commensurate magnetic phases of NaFe(WO) and MnWO
S. Biesenkamp, N. Qureshi, Y. Sidis +3
The structural distortion and magnetoelastic coupling induced through commensurate magnetism has been investigated by neutron diffraction in structurally related MnWO and NaFe(…
Domain dynamics in LiCuVO: Evidence for polarized nanoregions
Christoph P. Grams, Severin Kopatz, Daniel Brüning +5
LiCuVO is a model system of a 1D spin-1/2 chain that enters a planar spin-spiral ground state below its Néel temperature of 2.4 K due to competing nearest and next nearest neig…
