Direct Observation of Interfacial Dzyaloshinskii-Moriya Interaction from Asymmetric Spin-wave Propagation in W/CoFeB/SiO2 Heterostructures Down to Sub-nanometer CoFeB Thickness
Nonreciprocal spin wave propagation in magnonic waveguides with the presence of interfacial Dzialoshinskii–Moriya interaction: different frequencies, amplitudes, and mode profiles.
