Restructuring in bimetallic core-shell nanoparticles: Real time observation
Nobutomo Nakamura, Koji Matsuura, Akio Ishii +1
The formation process of core-shell bimetallic nanoparticles synthesized by sputtering onto a substrate is observed in real time using an originally developed acoustic technique. T…
The angular dependence of magnetization dynamics induced by a GHz range strain pulse
Kakeru Tojo, Akira Nagakubo, Hirotsugu Ogi
The dynamics of magnetization is important in spintronics, where the coupling between phonon and magnon attracts much attention. In this work, we study the angular dependence of th…
Elastic constant of dielectric nano-thin films using three-layer resonance studied by picosecond ultrasonics
Hiroki Fukuda, Akira Nagakubo, Hirotsugu Ogi
Elastic constants and sound velocities of nm-order thin films are essential for designing acoustic filters. However, it is difficult to measure them for dielectric thin films. In t…
