YBa, Cu~Oy (YBCO) thin films were in-situ prepared on MgO(001) substrates with vicinal angles toward [100]Mg'O.'[001]YBCO tilted from substrate surface normal only toward [001]MgO. With increasing the vicinal angles, the angle between [001]YBCO and [001]MgO and the rocking curve width were increased

Yttrium-Barium-Copper-Oxide ( \(\left.\mathrm{YBa}_{2} \mathrm{Cu}_{3} \mathrm{O}_{\mathrm{x}}\right)\) thin films are prepared using laser ablation. The \(<100\rangle\) orientation of the \(0.2-0.3 \mu \mathrm{m}\) thin film is controlled using both substrate temperature and deposited buffer layers
Samples of YBa2Cu30 x were prepared by solid state reaction and characterized by resistivity and magnetic measurements, x-ray diffraction, and electron microprobe analysis. The oxygen pressure was measured directly as function of temperature under isochoric conditions with minimized free volume. DTA
