Abstract
ABSTRACTThe shape of the normalized temperature derivative of the dc susceptibility provides useful information about superconducting materials. We propose that the position of the derivative peak be defined as the transition temperature Tc and the width of this peak define its sharpness.

= 90 K). By utilizing the maximum entropy method (MEM) the Raman bands were separated from the luminescent background. Our results clearly demonstrate significant enhancement of Raman activity, indicative of strong electron–phonon coupling, below the superconducting transition temperature, together with low-temperature ordering of the copper ions in their lattice sites. Several bands may also be attributed to defects of the oxygen lattice, some of which disappear as the reordering occurs.
