The spin torque (ST) efficiency and energy barrier of domain wall (DW) depinning are investigated by analyzing the telegraph noise in nanostructured ferromagnetic Pt/Co/Pt films. The telegraph noise is generated by applying both a magnetic field and

We developed a time-resolved magneto-optical Kerr effect microscope system to investigate ultrafast magnetization dynamics. Based on the pump-probe method, 0.1-ps time resolution was achieved by use of a fs Ti:Sapphire laser. The magnetization dynami

We propose a method to reduce the operation current of domain-wall (DW) motion in ferromagnetic nanowires with perpendicular magnetic anisotropy. It is based on the phenomena that a DW placed in wedged nanowire geometry moves spontaneously without an

We examine magnetic domain wall motion in metallic nanowires Pt-Co-Pt. Regardless of whether the motion is driven by either magnetic fields or current, all experimental data fall onto a single universal curve in the creep regime, implying that both t

The electric control of the motion of multiple domain walls (DWs) is demonstrated by using the Pt/Co/Pt nanotracks with perpendicular magnetic anisotropy. Because of the weak microstructural disorders with a small DW propagation field (approximately

We report here an experimental technique to generate spinwaves using femtosecond laser pulses. The femtosecond laser pulses induce ultrafast demagnetization, which causes the propagation of the spinwaves from the laser spot. The observed spinwaves ex
