Novel structural and electronic investigations on ternary and quaternary implantations in La-Cuprate HTC-Ceramic superconductors

Various alkaline earth, transition and lanthanide cation implantations have been carefully undertaken in La-Cuprate HTC-ceramic superconducting material. On these new materials extensive investigations of X-ray diffraction analysis and the temperature dependence of electrical conductivity have been carried out, compared and discussed in detail. The author's view on the electronic band structure of the reported materials was put forward
