An oxide-diluted magnetic semiconductor: Mn-doped ZnO
TL;DR: In this article, the lattice constants of both a and c axes of wurtzite Zn1−xMnxO films (x < 0.35) increase and the band gap expands although considerable in-gap absorption develops.
Journal ArticleDOI
Magnetic properties of Mn-doped ZnO
Tomoteru Fukumura,Zhengwu Jin,Masashi Kawasaki,T. Shono,T. Hasegawa,Shin-ya Koshihara,Hideomi Koinuma +6 more
TL;DR: In this paper, the magnetic properties of an oxide-diluted magnetic semiconductor (DMS), Zn0.64Mn 0.36O, were investigated and the temperature dependence of the magnetization showed a spin-glass behavior with the large magnitude of the Curie-Weiss temperature.
Journal ArticleDOI
High throughput fabrication of transition-metal-doped epitaxial ZnO thin films: A series of oxide-diluted magnetic semiconductors and their properties
Zhengwu Jin,Tomoteru Fukumura,Megumi Kawasaki,K. Ando,Hidekazu Saito,Takashi Sekiguchi,Y.-Z. Yoo,Makoto Murakami,Yuji Matsumoto,T. Hasegawa,Hideomi Koinuma +10 more
TL;DR: Combinatorial laser molecular-beam epitaxy method was employed to fabricate epitaxial ZnO thin films doped with all the 3d transition metal (TM) ions in a high throughput fashion as discussed by the authors.
Journal ArticleDOI
Magneto-optical properties of ZnO-based diluted magnetic semiconductors
K. Ando,Hidekazu Saito,Zhengwu Jin,Tomoteru Fukumura,Masashi Kawasaki,Yuji Matsumoto,Hideomi Koinuma +6 more
TL;DR: The magnetic circular dichroism (MCD) spectra of Zn1−xTMxO (TM=Sc, Ti, V, Cr, Mn, Co, Ni, and Cu) films were measured to clarify their magneto-optical properties as mentioned in this paper.
Journal ArticleDOI
Combinatorial Laser Molecular Beam Epitaxy (MBE) Growth of Mg Zn O Alloy for Band Gap Engineering
Yuji Matsumoto,Makoto Murakami,Zhengwu Jin,Akira Ohtomo,Mikk Lippmaa,Masashi Kawasaki,Hideomi Koinuma +6 more
TL;DR: In this paper, a new combinatorial synthesis system integrating a shadow mask into a laser MBE chamber was developed for fabricating a number of crystalline films with different compositions under programmed temperature and pressure conditions.
