Eigenmodes of Neel skyrmions in ultrathin magnetic films
Vanessa Li Zhang, Chen Guang Hou, Kai Di +5
The static and dynamic states of Néel skyrmions in ultrathin ferromagnetic films with interfacial Dzyaloshinskii-Moriya interaction (DMI) have been micromagnetically simulated as f…
In-plane angular dependence of the spin-wave nonreciprocity of an ultrathin film with Dzyaloshinskii-Moriya interaction
Vanessa Li Zhang, Kai Di, Hock Siah Lim +6
The nonreciprocal propagation of spin waves in an ultrathin Pt/Co/Ni film has been measured by Brillouin light scattering. The frequency nonreciprocity, due to the interfacial Dzya…
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…
Spin-wave nonreciprocity based on interband magnonic transitions
Kai Di, Hock Siah Lim, Vanessa Li Zhang +2
We theoretically demonstrate linear spin-wave nonreciprocity in a Ni80Fe20 nanostripe waveguide, based on interband magnonic transitions induced by a time-reversal and spatialinver…
Comment on "Physical Origin and Generic Control of Magnonic Band Gaps of Dipole-Exchange Spin Waves in Width-Modulated Nanostrip Waveguides" [K.-S. Lee, D.-S. Han, and S.-K. Kim, PRL 102, 127202 (2009), arXiv:0811.0411]
K. Di, H. S. Lim, V. L. Zhang +4
In Ref. [PRL 102, 127202 (2009)] Lee et al. reported the existence of large magnonic bandgaps in one-dimensional width-modulated Permalloy nanostripe waveguides based on OOMMF simu…
