摘要：

The magnetic properties of the ferroic (1-x)PbFe2/3W1/3O3-xPbTiO(3) system with various compositions in the range xis an element of(0,0.50) were investigated. A magnetodielectric coupling is proved by an anomaly of the magnetic hysteresis loop found in the Curie range of temperatures for the relaxor PbFe2/3W1/3O3 ceramic. Two types of superexchange magnetic interactions and a succession of magnetic transitions with Neel temperatures dependent on the composition were found in the system. The present results confirm the hypothesis of a relationship between the magnetic properties and the nanopolar ordering in the relaxor-ferroelectric system. (C) 2003 American Institute of Physics.
