Propagating spectroscopy of backward volume spin waves in a metallic FeNi film
- Department of Physics, Keio University, Hiyoshi 3-14-1, Yokohama 223-8522 (Japan)
We report a propagating spin wave spectroscopy for a magnetostatic backward volume spin wave in a metallic Fe{sub 19}Ni{sub 81} film. We show that the mutual-inductance between two independent antennas detects a small but clear propagation signal of backward volume spin waves. All experimental data are consistent with the time-domain propagating spin-wave spectroscopy. The control of propagating backward spin wave enables to realize the miniaturize spin-wave circuit.
