Accurate simulations of magnetic excitations in the neutron simulation package McStas
Silas B. Schack, Kristine M. L. Krighaar, Emma Y. Lenander +1
A new component for the accurate simulation of neutron scattering from magnetic excitations has been developed for the neutron ray-tracing software McStas. The component SpinWave_B…

Approximate resolution convolution function for fitting a dispersion gap measured on a triple-axis spectrometer
Emma Y. Lenander, Silas B. Schack, Kim Lefmann +1
We present an analytic convoluted-gap function, eq. 11 in the manuscript, for fitting dispersion gaps measured on triple-axis spectrometers (TAS). At the gap, the instrumental reso…

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…
