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…
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…
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…
