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…
KVASIR: A backscattering neutron spectrometer for hard condensed matter at ESS
Amalie F. Davidsen, Kristine M. L. Krighaar, Pascale P. Deen +1
We present the instrument concept for KVASIR, a backscattering indirect time-of-flight neutron spectrometer for the European Spallation Source (ESS). KVASIR will probe low lying ex…
Characterizing the diffuse continuum excitations in the classical spin liquid -YMnO
Jakob Lass, Emma Y. Lenander, Kristine M. L. Krighaar +5
We extend previous inelastic neutron scattering results on the geometrically frustrated antiferromagnet hexagonal-YMnO, which has been suggested to belong to the class of class…
Origin of correlated diffuse scattering in the hexagonal manganites
Tara N. Tošić, Arkadiy Simonov, Nicola A. Spaldin
We use a combination of first-principles density functional calculations and spin-dynamics simulations to explain the unusual diffuse inelastic neutron scattering in the hexagonal…
Dipolar Spin Ice Under Uniaxial Pressure
Richard Edberg, Lise Ørduk Sandberg, Ingrid Marie Bergh Bakke +8
The magnetically frustrated spin ice family of materials is host to numerous exotic phenomena such as magnetic monopole excitations and macroscopic residual entropy extending to lo…
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…
