Structural and Electrical Properties of Fluorine Doped (Bi, Pb)-1212 Ceramics
In the aim to test the effect of fluorine doping on structural and electrical properties of semiconducting Bi(Pb)-1212 phase, bulk samples with nominal composition of Bi0.4Pb0.35Sr2Y0.8Ca0.2Cu2.05O (y) F (x) with x=0,0.2,0.4 ...
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 ...
