Abstract

By coupling a rotating anode powder diffractometer with a continUOUS-flOW liquid helium-cooled cryostat and a split-coil superconducting magnet, Rietveld-quality powder diffraction data have been obtained between 5 and 3 15 K in magnetic fields reaching 4 T. A typical experiment quantifying both the phase composition and changes in the unit cell dimensions and phase volume(s) may be carried Out in as little as ten to twenty minutes. A few hours long experiment is sufficient to provide detailed information about the individual atomic parameters. Both massive and subtle field-induced structural changes have been detected, providing structural data needed to develop a better understanding of structureproperty relationships of solids.
