PRESSURE EFFECT ON CRYSTAL STRUCTURE OF BISMUTH TUNGSTATE Bi2WO6
Full text linkThe structural phase transitions in Bi2WO6 have been investigated by neutron diffraction and Raman spectroscopy at high-pressures. Two phase transitions under pressure were ob-served in the pressure range up to 7 GPa, which are associated with rotations and tilts of the octahedral WO6.The work was supported by the Russian Foundation for Basic Research, grant RFBR N19-52-45009 IND_a
