P. Shang et al., Locating dysprosium dopant atoms in the Bi2Sr2CaCu2Oy unit cell: direct-space chemical crystallography, PHIL MAG L, 79(9), 1999, pp. 741-745
The position of Dy in the unit cell of Bi2Sr2CaCu2Oy has been determined by
a real-space method. This is compared with the reciprocal-space atom locat
ion by channelling-enhanced microanalysis (ALCHEMI) method.
