Abstract
A dielectric and Raman measurements study of phase transitions in (Ba0 .6Sr0.4)(Ti1-xNix)O-3 ceramics with x ranging from 0.0 to 3.0 is repor ted. Both temperature transitions of respectively cubic-tetragonal and tetragonal-orthorhombic phase transitions are shifted to lower temper ature with increasing Ni content. A change from normal to diffused pha se transition is also observed in Ni-doped samples. This behavior is a ccompanied with a broadening of Raman lines. Theses observations may b e attributed to local disorder of Ni ions in the B site of the ABO(3) perovskite.
