Polycrystalline samples of La1.8M0.20Cu1-xMnxO4 (0d”xd”0.20) 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 La1.8M0.20Cu1-xMnxO4 samples. The La1.8Sr0.20Cu1-xMnxO4 sample was found to be superconducting while La1.8Ca0.20Cu1-xMnxO4 sample was found to be magnetoresistive.
