We demonstrated two pulse control of magnetization precession of GdFe films using low-power pulse of 18 &#x03BC;J/cm<sup>2</sup>. Our result suggests that the accurate control of magnetization precession should be achieved only by the low-power excitation.
This paper presents future display systems, such as, bendable flexible display with plasma technologies and a spatial light modulator driven by spin polarized current (Spin-SLM) for 3D holography TV. As a flexible display, a Luminous Array Film (LAFi) with the plasma tube is the world first film type display that realizes a bendable super large area(More)
Optical and magneto-optical properties of amorphous Gd 22 Fe 78 (GdFe) thin films prepared by direct current (DC) sputtering on thermally oxidized substrates were characterized by the combination of spectroscopic ellipsometry and magneto-optical spectroscopy in the photon energy range from 1.5 to 5.5 eV. Thin SiN x and Ru coatings were used to prevent the(More)
We have developed an active matrix-addressed magneto-optical spatial light modulator driven by spin-transfer switching (spin-SLM) which has a 100 × 100 array pixel layout with a 2 µm pixel pitch. It has pixel-selection-transistors and logic circuits which convert serial data into parallel data to reduce input terminals. We have confirmed successful(More)
— We propose a new type of magneto-optical (MO) Spatial Light-Modulation device, driven by spin-polarized current flow, i.e. Spin Transfer Switching (STS-SLM). Its basic operation and characteristics were experimentally confirmed. The proposed SLM device has a spatial resolution as small as several hundred nanometers, and an ultra-high drive speed of(More)
