Propagating spectroscopy of backward volume spin waves in a metallic FeNi film

We report a propagating spin wave spectroscopy for a magnetostatic backward volume spin wave in a metallic Fe19Ni81 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 consiste...

Description
Summary:We report a propagating spin wave spectroscopy for a magnetostatic backward volume spin wave in a metallic Fe19Ni81 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.
