Abstract
The influence of sintering temperatures and nominal starting compositions on the phase contents of polycrystalline Bi2Sr2Can-1CunO4+2 n samples are reported. After every sintering the samples were characterized with X-ray diffraction and magnetic AC susceptibility measurements. For Mössbauer studies, in each case also a corresponding specimen containing57Fe was synthetized. The identification of various superconducting Bi2Sr2Can-1CunO4+2 n phases on the basis of Mössbauer spectra consisting usually of three quadrupole doublets is discussed.
