Novel K Rattling: A New Route to Thermoelectric Materials?
Elvis Shoko, Y. Okamoto, Gordon J Kearley +2
We have performed ab initio molecular dynamics (MD) simulations to study the alkali-metal dynamics in the Al-doped (KAl0.33W1.67O6 and RbAl0.33W1.67O6) and undoped (KW2O6 and RbW2O…
Spinodal Decomposition in the TiO2-VO2 System
Zenji Hiroi, Hiroaki Hayamizu, Toru Yoshida +4
Spinodal decomposition is a ubiquitous phenomenon leading to phase separation from a uniform solution. We show that a spinodal decomposition occurs in a unique combination of two r…
Magnetic Properties of the Spin-1/2 Deformed Kagome Antiferromagnet Edwardsite
Hajime Ishikawa, Yoshihiko Okamoto, Zenji Hiroi
We prepared a powder sample of edwardsite Cd2Cu3(SO4)2(OH)6 4H2O, which is a new candidate compound for the spin-1/2 kagome antiferromagnet, and studied its magnetic properties by…
Breathing Pyrochlore Lattice Realized in A-Site Ordered Spinel Oxides LiGaCr4O8 and LiInCr4O8
Yoshihiko Okamoto, Gøran J. Nilsen, J. Paul Attfield +1
A unique type of frustrated lattice is found in two A-site ordered spinel oxides, LiGaCr4O8 and LiInCr4O8. Because of the large size mismatch between Li+ and Ga3+/In3+ ions at the…
