Crystal and Magnetic Structures of Ba2BTeO6 (B=Cu, Ni, Zn)
Ba2CuTeO6 and Ba2NiTeO6 are compounds with structures related to that of the proposed spin liquid Ba3CuSb2O9. The space group and nature of the B-site ordering in Ba3CuSb2O9... -
Subtle magnetic phase transitions in multiferroic BiFeO3
This experiment seeks to probe the magnetic structure of multiferroic BiFeO3 and its evolution on lowering temperature, with the specific aim of identifying magneto-structural... -
Electronically-driven structural transition in Ti-doped Ca3Ru2O7
The purpose of the experiment is to determine the effect of titanium doping on the structural and magnetic transitions of Ca3Ru2O7. The pure material undergoes a Néel transition... -
The high temperature phases of multiferroic YMnO3
Hexagonal YMnO3 is a well-studied, but poorly understood, multiferroic material, which adopts the 'geometric' mechanism of ferroelectric distortion, rather than the more normal... -
The elusive ¿cubic¿ phase of BiFeO3 and related materials
We wish to probe the suggested existence of a high-temperature cubic perovskite phase in the multiferroic material BiFe0.7Mn0.3O3. The parent phase of this material, BiFeO3, was...
