Recent advances in the study of quasicrystals
Fisher IR; Kramer MJ; Goldman AI.
Micron ; 31(5): 469-73, 2000 Oct.
Artigo em Inglês | MEDLINE | ID: mdl-10831290

RESUMO

Some recent advances in the study of quasicrystals at Ames Laboratory are reviewed. In particular, growth from the melt of large, high-quality, single-grain quasicrystals is described in detail for icosahedral R-Mg-Zn and decagonal Al-Ni-Co. In addition, the magnetic properties of the rare-earth-containing icosahedral R-Mg-Zn quasicrystals are discussed.
