Field-induced quasi-bound state within the two-magnon continuum of a square-lattice Heisenberg antiferromagnet
F. Elson, M. Nayak, A. A. Eberharter +14
Quantum magnets in two dimensions display strong quantum interaction effects even when magnetically ordered. Using the metal-organic framework material CuF(DO)(pyz), we…
Refined spin Hamiltonian on the Cairo pentagonal lattice of Bi2Fe4O9
Emma Y. Lenander, Frida B. Nielsen, Jakob Lass +14
The frustrated magnet Bi2Fe4O9 has been reported to exhibit complex spin dynamics coexisting with conventional spin wave excitations. The magnetic Fe3+ (S = 5/2) ions are arranged…
Phonon dispersion of quantum paraelectric SrTiO3 in electric fields
Henrik Jacobsen, Marek Barthkowiak, Tobias Weber +4
Here we report on an elastic and inelastic neutron scattering study addressing the effect of electric fields on quantum paraelectric SrTiO3. Our elastic scattering results find sma…
Correlation of Structural and Magnetic Properties of RFeO3 (R=Dy, Lu)
Banani Biswas, Pavel Naumov, Federico Motti +7
In orthoferrites the rare-earth (R) ion has a big impact on structural and magnetic properties in particular the ionic size influences the octahedral tilt and the R3+- Fe3+ interac…
Magnetic order in the quasi-one-dimensional Ising system RbCoCl
N. P. Hänni, D. Sheptyakov, M. Mena +9
The dynamical properties of free and bound domain-wall excitations in Ising-chain materials have recently become the focus of intense research interest. New materials and spectrome…
Experimental determination of the magnetic interactions of frustrated Cairo pentagon lattice materials
Manh Duc Le, Elisa M. Wheeler, Jaehong Jeong +14
We present inelastic neutron scattering measurements of the Cairo pentagon lattice magnets BiFeO and BiFeOF, supported by high field magnetisation measur…
Magnetic ground state and magnon-phonon interaction in multiferroic h-YMnO
S. L. Holm, A. Kreisel, T. K. Schäffer +14
Inelastic neutron scattering has been used to study the magneto-elastic excitations in the multiferroic manganite hexagonal YMnO. An avoided crossing is found between magnon an…
