Growth and characterization of REBa2Cu3O7− superconductor single crystals obtained from xenotime mineral

Depth-Sensing Indentation on REBa2Cu3O7−δ Single Crystals Obtained from Xenotime Mineral

“…The chemical procedure to obtain the natural mixture of trivalent rare earth oxides RE 2 O 3 from xenotime mineral is described in detail elsewhere [5]. A CuO-BaO self-flux method similar to that described by Schneemeyer et al [6] and Wang et al [7] was performed in order to grow large obtained.…”

“…A CuO-BaO self-flux method similar to that described by Schneemeyer et al [6] and Wang et al [7] was performed in order to grow large obtained. These samples were characterized by XRD, SEM and electrical resistivity and the results were described elsewhere [5].…”

“…This provide an alternative non-expensive route to prepare high-T c superconductor isostructural to YBa 2 Cu 3 O 7-G that does not demand high purity Yttrium or other pure lanthanide element on Y site. Polycrystalline, melt-textured and single crystals samples using rare earth elements extracted from xenotime has been successfully grown with good superconductor properties [3][4][5]. 4 The growth of large and good quality single crystals of hightemperature superconductors is necessary because it is important to measure their physical properties with high accuracy as well as to develop new devices.…”
