Propagating spin wave (PSW) has been mainly studied by using micro-wave antenna for realizing future’s spin-based logic devices. Nowadays, pulse laser-induced PSW is actively being investigated in magnetic metals and insulators. In magnetic metals, which have much smaller propagation length, an excitation mechanism and detail properties of PSW are not well understood. In particular, excitation mechanism has a fundamental issue because of heating effect. Here, we report propagating properties depending on 80NiFe-(Py)-films thickness for pulse laser-induced spin wave.
