    • Abstract

       

      57Fe Mössbauer investigations at 300K have been carried out on V,Mn substituted YBa2Cu3O7−δ system. Preliminary studies show that for small concentration of V (4%), Fe occupies preferentially the Cu(1) site whereas for the same concentration of Mn, Fe prefers the Cu(2) site. It is suggested that for low concentrations V has a preference for Cu(2) site whereas Mn prefers Cu(1) site in the 1-2-3 lattice.
