Synthesis Growth and Characterization of Mn doped La1.8Sr0.20CuO4
Polycrystalline samples of La1.8Sr0.20Cu1-yMnyO4 (0≤y≤0.15) were synthesized by solid state reaction method. The phase purity was confirmed by powder X-ray diffraction. The scanning electron microscopy was done on the La1.8Sr0.20Cu1-yMnyO4 (0≤y≤0.15) samples. The superconductivity and Transition temperature were studied by four probe resistivity temperature method. The transition temperatures were measured nearly 37 k and were unchanged on Mn doping at Cu site in La1.8Sr0.20CuO4.
