Confined dipole and exchange spin waves in a bulk chiral magnet with Dzyaloshinskii-Moriya interaction
Ping Che, Ioannis Stasinopoulos, Andrea Mucchietto +5
The Dzyaloshinskii-Moriya interaction (DMI) has an impact on excited spin waves in the chiral magnet CuOSeO by means of introducing asymmetry on their dispersion relations.…
Surface pinning and triggered unwinding of skyrmions in a cubic chiral magnet
Peter Milde, Erik Neuber, Andreas Bauer +2
In the cubic chiral magnet FeCoSi a metastable state comprising of topologically nontrivial spin whirls, so-called skyrmions, may be preserved down to low temperature…
Field-induced reorientation of helimagnetic order in CuOSeO probed by magnetic force microscopy
Peter Milde, Laura Köhler, Erik Neuber +6
CuOSeO is an insulating skyrmion-host material with a magnetoelectric coupling giving rise to an electric polarization with a characteristic dependence on the magnetic fiel…
Microwave spectroscopy of the low-temperature skyrmion state in Cu2OSeO3
Aisha Aqeel, Jan Sahliger, Takuya Taniguchi +7
In the cubic chiral magnet Cu2OSeO3 a low-temperature skyrmion state (LTS) and a concomitant tilted conical state are observed for magnetic fields parallel to <100>. In this work,…
Lattice dynamics and coupled quadrupole-phonon excitations in CeAuAl
B. -Q. Liu, P. Čermák, C. Franz +2
We report first principles calculations of the structural parameters and phonon dispersion of the tetragonal non-centrosymmetric heavy fermion compound CeAuAl. Taking into acco…
Ultra-high vacuum compatible preparation chain for intermetallic compounds
A. Bauer, G. Benka, A. Regnat +2
We report the development of a versatile material preparation chain for intermetallic compounds that focuses on the realization of a high-purity growth environment. The preparation…
