Journal ArticleDOI
Breathing Pyrochlore Lattice Realized in A -Site Ordered Spinel Oxides LiGaCr 4 O 8 and LiInCr 4 O 8
TL;DR: A parameter, the breathing factor B(f), is introduced, which quantifies the degree of frustration in the pyrochlore lattice: J'/J, where J' and J are nearest-neighbor magnetic interactions in the large and small tetrahedra, respectively.
Journal ArticleDOI
Tunable thermal expansion in framework materials through redox intercalation
Jun Chen,Qilong Gao,Andrea Sanson,Xingxing Jiang,Qingzhen Huang,Alberto Carnera,Clara Guglieri Rodriguez,Luca Olivi,Lei Wang,Lei Hu,Kun Lin,Yang Ren,Zheshuai Lin,Cong Wang,Lin Gu,Jinxia Deng,J. Paul Attfield,Xianran Xing +17 more
TL;DR: It is shown that redox intercalation offers an effective method to control thermal expansion from positive to zero to negative by insertion of Li ions into the simple negative thermal expansion framework material ScF3, doped with 10% Fe to enable reduction.
Journal ArticleDOI
Pressure-Induced Intermetallic Valence Transition in BiNiO3
Masaki Azuma,Sandra Carlsson,Jennifer A. Rodgers,Matthew G. Tucker,Masahiko Tsujimoto,Shintaro Ishiwata,Seiji Isoda,Yuichi Shimakawa,Mikio Takano,J. Paul Attfield +9 more
TL;DR: High-pressure neutron diffraction measurements and bond valence sum calculations show that the pressure-induced melting of the charge disproportionated state leads to a simultaneous charge transfer from Ni to Bi, so that the high-pressure phase is metallic Bi(3+)Ni( 3+)O3.
Journal ArticleDOI
Electronic Tuning of Two Metals and Colossal Magnetoresistances in EuWO1+xN2-x Perovskites
TL;DR: Both the Eu and W oxidation states and the hole/electron doping are tuned by varying the O/N ratio, and colossal magnetoresistances (CMR) are observed in the least doped sample.
Journal ArticleDOI
High pressure synthesis of late rare earth RFeAs(O,F) superconductors; R = Tb and Dy.
Jan-Willem G. Bos,George B. S. Penny,Jennifer A. Rodgers,Dmitry A. Sokolov,Andrew Huxley,J. Paul Attfield +5 more
TL;DR: In this article, a new TbFeAs(O,F) and DyFeAs (O, F) superconductors with critical temperatures T(c) = 46 and 45 K and very high critical fields, >or=100 T, have been prepared at 1100-1150 degrees C and 10-12 GPa.
