Abstract

This study is focused on the phase separation phenomena in Fe(Se,Te) materials. In particular, it investigates the effect of a high temperature and long time annealing treatment on morphostructural and superconducting properties of bulk samples. The synthesis of Fe(Se,Te) compounds was carried out through a melting route, and the materials were characterized in their morphostructural and magnetic properties. The obtained compounds possess a high degree of inhomogeneity due to dendritic precipitates of secondary phases in a superconducting tetragonal matrix. The high temperature annealing treatment induces a morphological evolution of the material and leads to the structuration of two distinct superconducting phases. © 2002-2011 IEEE.
