Universality of the helimagnetic transition in cubic chiral magnets: Small angle neutron scattering and neutron spin echo spectroscopy studies of FeCoSi
L. J. Bannenberg, K. Kakurai, P. Falus +8
We present a comprehensive Small Angle Neutron Scattering (SANS) and Neutron Spin Echo Spectroscopy (NSE) study of the structural and dynamical aspects of the helimagnetic transiti…
Magnetic relaxation phenomena in the Chiral Magnet FeCoSi: An ac susceptibility study
L. J. Bannenberg, A. L. E. Lefering, K. Kakurai +4
We present a systematic study of the ac susceptibility of the chiral magnet FeCoSi with = 0.30 covering four orders of magnitude in frequencies from 0.1 Hz to 1 kHz…
Nonreciprocal propagation of surface acoustic wave in Ni/LiNbO3
R. Sasaki, Y. Nii, Y. Iguchi +1
We have investigated surface acoustic wave propagation in Ni/LiNbO hybrid devices. We have found the absorption and phase velocity are dependent on the sign of wave vector in a…
Nonreciprocal magnon propagation in a noncentrosymmetric ferromagnet
Y. Iguchi, S. Uemura, K. Ueno +1
Relativistic spin-orbit interaction drastically modifies electronic band and endows emergent functionalities. One of the example is the Rashba effect. In noncentrosymmetric systems…
Giant directional dichroism of terahertz light in resonance with magnetic excitations of the multiferroic oxide BaCoGeO
I. Kezsmarki, N. Kida, H. Murakawa +3
We propose that concurrently magnetic and ferroelectric, i.e. multiferroic, compounds endowed with electrically-active magnetic excitations (electromagnons) provide a key to produc…
