dc.description.abstract | Brillouin light scattering has been employed to study the magnetic-field dependence of the discrete spin waves in permalloy Ni80 Fe20 nanowires. When a small magnetic field is applied transverse to the nanowire, the results reveal a low-frequency mode, which is absent in the longitudinal case. A Hamiltonian-based microscopic theory for nanowires with inhomogeneous magnetization shows that the appearance of this mode, along with its higher-field behavior, is a significant consequence of a small easy-plane single-ion anisotropy at the nanowire surface. The calculations provide a good description of experimental data for both the transverse and longitudinal cases. © 2006 The American Physical Society. | |
