Abstract
Effect of Fe3O4 segregation at grain boundaries on theelectrical transport and magnetic properties ofLa0.67Ca0.33MnO3 is investigated. The experimentalresults show that the Fe3O4 segregation not only shiftsthe paramagnetic–ferromagnetic transition temperature ofLa0.67Ca0.33MnO3 to a lower temperature region butalso induces a new transition in a lower temperature region. Meanwhile,the transition processes observed in both the resistivity andmagnetization curves are obviously widened. Compared to pureLa0.67Ca0.33MnO3, we assume that theFe3O4 segregation level at the grain boundaries canmodify the electrical transport and magnetic properties ofLa0.67Ca0.33MnO3.
