Complex 5d magnetism in a novel S = ½ trimer system, the 12L hexagonal perovskite Ba4BiIr3O12
Miiller, Wojciech; Dunstan, Matthew T; Huang, Zixin; Mohamed, Zakiah; Kennedy, Brendan J; Avdeev, Maxim; Ling, Chris DPublished 2013The 12L hexagonal perovskite Ba4BiIr3O12 has been synthesized for the first time and characterized using high-resolution neutron and synchrotron x-ray diffraction as well as physical properties measurements. The structure ...Open AccessArticle -
Experimental Observation and Computational Study of the Spin-gap Excitation in Ba3BiRu2O9
Ling, Chris D; Huang, Zixin; Kennedy, Brendan J; Rols, S; Johnson, M R; Zbiri, M; Kimber, S A J; Hudspeth, J; Adroja, D T; Rule, K C; Avdeev, Maxim; Blanchard, Peter E RPublished 2016Ba3BiRu2O9 is a 6H-type perovskite compound containing face-sharing octahedral M2O9 (M = Ir, Ru) dimers, which are magnetically frustrated at low temperatures. On cooling through T∗ = 176 K, it undergoes a pronounced ...Open AccessArticle -
The key role of bismuth in the magnetoelastic transitions of Ba3BiIr2O9 and Ba3BiRu2O9 as revealed by chemical doping
Blanchard, Peter E R; Huang, Zixin; Kennedy, Brendan J; Liu, Samuel; Miiller, Wojciech; Reynolds, Emily; Zhou, Qingdi; Avdeev, Maxim; Zhang, Z; Aitken, J B; Cowrie, B C C; Jang, L-Y; Li, Sean; Ling, Chris DPublished 2014The key role played by bismuth in an average intermediate oxidation state in the magnetoelastic spin-gap compounds Ba3BiRu2O9 and Ba3BiIr2O9 has been confirmed by systematically replacing bismuth with La3+ and Ce4+. Through ...Open AccessArticle -
Protocols for optical quantum metrology
Huang, ZixinPublished 2018-04-05This thesis explores various protocols which can be applied to quantum metrology, such that precision of the measurement can beat the best classical approaches. We first demonstrate that ancilla-assisted schemes can improve ...USyd AccessThesis -
Tuning the Giant Magnetoelastic Transition in Ba3BiIr2O9 and Ba3BiRu2O9
Huang, Zixin; Avdeev, Maxim; Kennedy, Brendan J; Knight, Kevin S; Zhou, Qingdi; Ling, Chris DPublished 2014We have experimentally investigated the effects of pressure on the magnetoelastic transitions associated with the opening of spin-gaps in Ba3BiIr2O9 and Ba3BiRu2O9. For both compounds, reducing the unit cell volume by ...Open AccessArticle
