he annealing influence onto the electrical and magnetic  behavior of magnetoresistive/insulator system
his investigation is mainly concerned with the effect of annealing temperature (600, 700, 800 and 900 °C) in air for (La0.7Ba0.3MnO3)1–x /(NiO)x with x = 0 and x = 0.10 samples. It was shown that the annealing temperature does not affect the structure and parameters of rhombohedral lattice of the samples. However, it is observed that the annealing treatment has ... إقراء المزيد
