All-optical switching in CoFeB-based artificial ferrimagnets

S. Li, T. Ueno, R. Takahashi, H. Wadati et autres

We demonstrate deterministic all-optical switching (AOS) triggered by single femtosecond laser pulses in CoFeB-based artificial ferrimagnets consisting of Co/Gd/CoFeB trilayers. We show that AOS in this trilayer system is primarily governed by the energetics of nonequilibrium demagnetization, rather than by the magnetic …

X-Ray Detected Ferromagnetic Resonance Spectrometer With an Out-of-Vacuum Photodetector

T. Ueno, Y. Takeichi, M.Mizuguchi, H. Iwasawa et autres

X-ray detected ferromagnetic resonance (XFMR) spectroscopy is an experimental technique for element-specific spin dynamics in the GHz regime and has been utilized to study spintronic materials. The XFMR signal is usually obtained by detecting X-ray excited optical luminescence (XEOL) emitted from a …
