Neutron scattering study on spin correlations and fluctuations in the transition-metal-based magnetic quasicrystal Zn-Fe-Sc
Taku J Sato, Shiro Kashimoto, Chihiro Masuda +5
Spin correlations and fluctuations in the 3d-transition-metal-based icosahedral quasicrystal Zn-Fe-Sc have been investigated by neutron scattering using polycrystalline samples. Ma…
Icosahedral quasicrystals in Zn-T-Sc (T=Mn, Fe, Co, Ni) alloys
Ryo Maezawa, Shiro Kashimoto, Tsutomu Ishimasa
Starting from the Zn17Sc3 cubic approximant, new quasicrystal alloys were searched by replacement of Zn with transition elements, T. In the cases of T=Mn, Fe, Co and Ni, new icosah…
Structure analysis of Zn-Mg-Ho icosahedral quasicrystal by modified Rietveld method using ellipsoid and sphere windows
Tsutomu Ishimasa, Kei Oyamda, Yasuomi Arichika +4
A structure analysis of Zn-Mg-Ho icosahedral quasicrystal was carried out by the powder X-ray diffraction method using synchrotron radiation (Lambda=0.73490 A) at SPring-8. The int…
New group of stable icosahedral quasicrystals: structural properties and formation conditions
Tsutomu Ishimasa, Yasushi Kaneko, Hiroshi Kaneko
Structural studies on the icosahedral quasicrystals in Zn-Mg-Sc, Cu-Ga-Mg-Sc, and Zn-Mg-Ti alloys as well as their corresponding 1/1 cubic approximants, have revealed that these qu…
