Effect of Re doping on structure and magneto-electrical properties of La1.2Re0.2Ca1.6Mn2O7 manganites
In this paper, the structural and magneto-electrical properties of the double layered La12Re0.2Ca1.6Mn2O7 manganites doped with Re=La, Pr, Eu, Y and Gd are presented. The results show that the decreasing of the ionic radii ...
Structural and Magneto-Transport Properties of Copper Doped Double Layered Manganites La1.4Ca1.6Mn2O7
Samples of La1.4Ca1.6Mn2-xCuxO7 with 0 <= x <= 0.075 were prepared by a solid state reaction and characterized. The cell parameters and volume increase with increasing doped content in all the samples. The metal-insulator ...
