The single phase multiferroic (Dy,Cu) – modified BFO
(BDFCO) and Dy modified BFO (BDFO) were prepared by a sol–gel
method. Then two composites, namely 0.85BDFCO–0.15BTO and 0.85
BDFO–0.15BTO, were prepared by the solid state reaction method and
their magnetic properties and the magnetoelectric coupling were
investigated.
