Asymmetric spin-wave dispersion due to Dzyaloshinskii-Moriya interaction in an ultrathin Pt/CoFeB film
Kai Di, Vanessa Li Zhang, Hock Siah Lim +4
Employing Brillouin spectroscopy, strong interfacial Dzyaloshinskii-Moriya interactions have been observed in an ultrathin Pt/CoFeB film. Our micromagnetic simulations show that sp…
Tuning the Band Structures of a 1D Width-Modulated Magnonic Crystal by a Transverse Magnetic Field
K. Di, H. S. Lim, V. L. Zhang +4
Theoretical studies, based on three independent techniques, of the band structure of a one-dimensional width-modulated magnonic crystal under a transverse magnetic field are report…
Direct observation of the Dzyaloshinskii-Moriya interaction in a Pt/Co/Ni film
Kai Di, Vanessa Li Zhang, Hock Siah Lim +6
The interfacial Dzyaloshinskii-Moriya interaction (DMI) in an in-plane anisotropic Pt(4nm)/Co(1.6nm)/Ni(1.6nm) film has been directly observed by Brillouin spectroscopy. It is mani…
Band structure of magnonic crystals with defects: Brillouin spectroscopy and micromagnetic simulations
Kai Di, Vanessa Li Zhang, Meng Hau Kuok +4
Using Brillouin spectroscopy, the first observation has been made of the band structures of nanostructured defect magnonic crystals. The samples are otherwise one-dimensional perio…
