Probing the real-space density of spin-entangled electrons
Federico Pisani, Leonie Spitz, Libor VojáÄek +12
On the textbook example of an isolated antiferromagnetic Heisenberg dimer, we demonstrate that the magnetic form factor and the magnetic electron density distribution can be extrac…
First-Order Spin-Reorientation Transition and Incomplete Softening of the Antiferromagnetic Resonance Mode in Multiferroic GdFe(BO)
I. N. Khoroshiy, S. A. Skorobogatov, S. E. Nikitin +3
The multiferroic ferroborate GdFe(BO) with huntite-type structure exhibits magnetic ordering below T = 38 K and contains two magnetic subsystems associated with Gd…
Phonon spectrum in the spin-Peierls phase of CuGeO
L. Spitz, A. Razpopov, S. Biswas +10
CuGeO has long been studied as a prototypical example of the spin-Peierls transition in a Heisenberg chain. Despite intensive investigation of this quasi-one-dimensio…
Competition Between Multiferroic and Magnetic Soliton Lattice States in DyFeO
S. E. Nikitin, N. D. Andriushin, Ã. S. FjellvÃ¥g +5
Simultaneous breaking of time reversal and inversion symmetries in multiferroics couples ferroelectricity to magnetism and is a source of unusual physical phenomena that can be use…
Easy-cone state mediating the spin reorientation in topological kagome magnet FeSn
L. Prodan, D. M. Evans, A. S. Sukhanov +7
We investigated temperature-driven spin reorientation (SR) in the itinerant kagome magnet FeSn using high-resolution synchrotron x-ray diffraction, neutron diffraction, mag…
Observation of the spiral spin liquid in a triangular-lattice material
N. D. Andriushin, S. E. Nikitin, Ã. S. FjellvÃ¥g +7
The spiral spin liquid (SSL) is a highly degenerate state characterized by a continuous contour or surface in reciprocal space spanned by a spiral propagation vector. Although the…
