Magneto-resistivity and magnetization investigations of YBCO superconductor added by nano-wires and nano-particles of titanium oxide
We study in this work the influence of titanium oxide (TiO 2 ) nano-wires (NWs) and nano-particles (NPs) addition on the flux trapping potential of YBa 2 Cu 3 O y (YBCO for brevity). Samples were characterized using various techniques, including X-rays diffraction, scanning electron microscopy, temp...
