Nonlinear Decay of Quantum Confined Magnons in Itinerant Ferromagnets
Kh. Zakeri, A. Hjelt, I. V. Maznichenko +2
Quantum confinement leads to the emergence of several magnon modes in ultrathin layered magnetic structures. We probe the lifetime of these quantum confined modes in a model system…

On the phonon dispersion relation of single-crystalline --FeSe
Khalil Zakeri, Tobias Engelhardt, Thomas Wolf +1
We report on the phonon spectrum probed at the --FeSe(001) surface by means of high-resolution electron energy-loss spectroscopy (HREELS). Single crystals of --FeSe are cleav…

Temperature Dependence of Magnetic Excitations: Terahertz Magnons above the Curie Temperature
H. J. Qin, Kh. Zakeri, A. Ernst +1
When an ordered spin system of a given dimensionality undergoes a second order phase transition the dependence of the order parameter i.e. magnetization on temperature can be well-…
