High-pressure anvil technique and neutron powder di4raction have been used to study the magnetic structures of cubic Pd 3 Mn and Pd 3 MnD 0.7 at pressure of 4.6 GPa and 4.2 GPa, respectively. The incommensurate helix structure of Pd 3 Mn is retained under pressure. The ferrimagnetic structure of Pd
The structure of a new calcium intergrowth tungsten bronze, Ca x WO 3 , prepared at P = 80 kbar and T = 1670 K, has been studied by high-resolution transmission electron microscopy and supplementary techniques. The unit-cell dimensions, determined from X-ray powder data, are: a = 10.1500( ), b = 7.4
The average structure of the orthorhombic antimony tungsten bronze, Sb 0.16 WO 3 , has been resolved by three-dimensional single-crystal X-ray diffraction (space group Pmmm, a av β«Ψβ¬ 7.4261(7), b av β«Ψβ¬ 10.2004(15), c av β«Ψβ¬ 3.8061(7) A s , and Z β«Ψβ¬ 5).
