A high resolution synchrotron x-ray powder diffraction study of the incommensurate modulation in the martensite phase of Ni2MnGa: Evidence for nearly 7M modulation and phason broadening
Sanjay Singh, V. Petricek, Parasmani Rajput +4
The modulated structure of the martensite phase of Ni2MnGa is revisited using high resolution synchrotron x-ray powder diffraction (SXRPD) measurements, which reveals higher order…
Nanoscale order in the frustrated mixed conductor La_{12-δ}$
Tobias Scherb, Simon A. J. Kimber, Christiane Stephan +8
We report a comprehensive investigation of the average and local structure of LaWO, which has excellent mixed proton, electron and oxide ion conduction suitable fo…
Charge order at the frontier between the molecular and solid states in Ba3NaRu2O9
Simon A. J. Kimber, Mark S. Senn, Simone Fratini +6
We show that the valence electrons of Ba3NaRu2O9, which has a quasi-molecular structure, completely crystallize below 210 K. Using an extended Hubbard model, we show that the charg…
120° Helical Magnetic Order in the Distorted Triangular Antiferromagnet alpha-CaCr2O4
S. Tóth, B. Lake, S. A. J. Kimber +9
α-CaCr2O4 is a distorted triangular antiferromagnet. The magnetic Cr3+ ions which have spin-3/2 and interact with their nearest neighbors via Heisenberg direct exchange interaction…
Spin and Orbital Order of the Vanadium Spinel MgV2O4
Elisa M. Wheeler, Bella Lake, A. T. M. Nazmul Islam +4
We present a unique study of the frustrated spinel MgV2O4 which possesses highly coupled spin, lattice and orbital degrees of freedom. Using large single-crystal and powder samples…
Local moments and symmetry breaking in metallic PrMnSbO
Simon A. J. Kimber, Adrian H. Hill, Yu-Zhong Zhang +7
We report a combined experimental and theoretical investigation of the layered antimonide PrMnSbO which is isostructural to the parent phase of the iron pnictide superconductors. W…
