L. Laroussi et al., CRYSTALLOGRAPHIC AND MAGNETIC-PROPERTIES OF M-DOPED YBA2CU3O6-XMX)(3)O6+Y (M-CR, MN, NI) SUPERCONDUCTING COMPOUNDS(Y AND YBA2(CU1), Annales de chimie, 23(1-2), 1998, pp. 221-224
The present study is aimed at carrying out studies on Cr, Mn and Ni-do
ped YBaCuO powders and samples according to the formulae YBa2(CU1-xMx)
(3)O6+y where M = Cr, Mn, Ni and x = 0.00; 0.02; 0.05 and 0.10, in ord
er to determine the solubility limit, to have an idea on the location
sites of 3d metal ions (Cr, Mn and Ni) and the T-c evolution. X-ray po
wder diffraction and a.c susceptibility measurements were needed.
