WebFeb 24, 2016 · Using an optically driven high-current picosecond pulse source in combination with time-resolved scanning Kerr microscopy probed by femtosecond laser … WebThe observed spin wave excitation spectra must be interpreted with spin wave quantization such as Damon-Eshbach mode separation. It was found that the spin wave quantization is related to the stripe magnetic domain structure in continuous film. The physical origin of the quantization is the partial reflection of the propagating spin wave at the ...

WebNov 11, 2024 · (C) The NV ESR frequencies ω ± are swept over the Damon-Eshbach spin-wave dispersion (black line) by tuning B 0. For any B 0 (1) < B 0 (2), ω − is resonant with spin waves of finite wavelength. At B 0 = B 0 (2), ω − is resonant with the ferromagnetic resonance (FMR). WebDec 16, 2003 · For values of k ≳10 4 a number of branches have significant surface character so that no single branch can be identified with the Damon‐Eshbach surface state. When the applied field is perpendicular to the surface a new type of surface spin wave occurs below the bulk manifold and is characterized by a complex wave vector normal to … how are sodium and potassium different
