Superconductivity has been a topical dicovery of materials research and condensed
matter physics since its discovery in 1911. It has seen applications appear within
cutting edge technology, yet the mechanism for this exotic quantum phenomena remains
unclear. This thesis is centred on the preliminary study on one family of the cuprate
high Tc superconductors, the La1.6−xNd0.4SrxCuO4 (Nd-LSCO) system. We were
able to synthesize single phase polycrystalline material of Nd-LSCO across its phase
diagram from x 0.02 to x 0.4. We were also able to grown three large, high quality
single crystal samples of this system at high doping, for the first time. Large single
crystals of La1.6−xNd0.4SrxCuO4 (x=0.17, 0.19 and 0.24) were successfully grown using
the traveling solvent floating zone technique. This thesis focuses on an introduction
to the relevant materials preparation and crystal growth techniques and a discussion
of some of the characterization of the samples which necessarily is involved in such a
systematic study. / Thesis / Master of Science (MSc)
