Effects of Dzyaloshinskii-Moriya interactions and dipole-dipole interactions on spin waves in finite-length ferromagnetic chains
Bushra Hussain, Michael Cottam
A spin-wave theory that includes the antisymmetric Dzyaloshinskii-Moriya exchange interactions and long-range dipole-dipole interactions is presented for finite-length ferromagneti…
Interplay between intra- and inter-nanowires dynamic dipolar interactions in the spin wave band structure of Py/Cu/Py nanowires
G. Gubbiotti, X. Zhou, Z. Haghshenasfard +3
We have studied both experimentally and theoretically the reprogrammable spin wave band structure in Permalloy(10nm)/Cu(5nm)/Permalloy(30nm) nanowire arrays of width w=280 nm and i…
Reprogrammable magnonic band structure of layered Permalloy/Cu/Permalloy nanowires
G. Gubbiotti, X. Zhou, Z. Haghshenasfard +2
Reprogrammability of magnonic band structure in layered Permalloy/Cu/Permalloy nanowires is demonstrated to depend on the relative orientation of the two layers magnetization. By u…
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…
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…
On the phase diagrams of the ferromagnetic superconductors ZrZn2 and UGe2
Michael G. Cottam, Diana V. Shopova, Dimo I. Uzunov
A general phenomenological theory is presented for the phase behavior of ferromagnetic superconductors with spin-triplet electron Cooper pairing. The theory accounts in detail for…
Microscopic Theory of Dipole-Exchange Spin Waves in Ferromagnetic Films: Linear and Nonlinear Processes
R. N. Costa Filho, M. G. Cottam, G. A. Farias
The linear and nonlinear processes in ferromagnetic films at low temperatures T<< Tc are studied in a microscopic theory. Both the long-range magnetic dipole-dipole and the Heisenb…
