Structural and Magnetic Properties of CdFe2O4 Thin Films Fabricated via Sputtering Method (2008)

Akamatsu, Hirofumi, Zong, Yanhua, Fujiki, Yosefu, Kamiya, Kazuaki, Fujita, Koji, Murai, Shunsuke, ...

CdFe2O4 thin films have been prepared by a sputtering method, and their structural and magnetic properties have been examined. As-deposited film shows magnetic transition like that of cluster-spin...

Scattering-based hole burning through volume speckles in a random medium with tunable diffusion constant (2008)

Murai, Shunsuke, Fujita, Koji, Hirao, Takayuki, Nakanishi, Kazuki, Hirao, Kazuyuki, Tanaka, Katsuhisa

A photoreactive random medium with tunable diffusion constant D is fabricated by infiltrating Sm2+-doped macroporous aluminosilicate glass with liquid crystal (LC). Time-resolved transmission...

Magneto-optical properties of transparent divalent iron phosphate glasses (2008)

Akamatsu, Hirofumi, Fujita, Koji, Murai, Shunsuke, Tanaka, Katsuhisa

We have prepared glasses having xFeO·(100−x)P2O5 (mol %) (x=50.0,54.0,57.1) compositions by melting under mild reducing condition and found that these glasses exhibit fairly high transmittance in...

Random lasers with coherent feedback from highly transparent polymer films embedded with silver nanoparticles (2008)

Meng, Xiangeng, Fujita, Koji, Zong, Yanhua, Murai, Shunsuke, Tanaka, Katsuhisa

We report on observations of random lasers with coherent feedback in highly transparent polymer films embedded with silver nanoparticles. The hybrid materials were fabricated via in situ synthesis...

Preparation and Optical Properties of Transparent Glass-Ceramics Containing Cobalt(II) Ions. (1998)

Tanaka, Katsuhisa, Mukai, Takashi, Ishihara, Tsuguo, Hirao, Kazuyuki, Soga, Naohiro

Transparent glass-ceramics containing ZnAl2O4:Co(2+) and LiGa5O8:Co(2+) crystallites have been prepared by heat treatment of glasses in the zinc aluminosilicate and lithium gallate silicate systems,...
