A new type of buffer layer, based on Nb doped YBa2Cu307 material, has been used for high quality HTSC ultrathin film fabrication. This new material represents a dielectric continuum of YBa2NbO 6 phase with YBa2Cu307 phase inclusions. The later serve as nuclei while growing ultrathin YBa2Cu307 film o
YBa2Cu3O7-δ thin films on Si substrates with Y2O3 and (Zr1-xYx)O2 buffer layers. The YBa2Cu3O7-δ-Y2O3 and Y2O3-(Zr1-xYx)O2 interfaces.

Electron paramagnetic resonance (EPR) measurements on polycrystalline YBazCu,07-d prepared via the citrates and the usual ceramic route of Bring the oxides and BaC03 are reported. The single phase samples of orthorhombic YBa2Bu3006.9 and tetmgonal YBa,Cu,O, obtained from a citrate precursor do not e
The concentration dependence of the transition temperature T c has been studied in the high-T c compounds (Y~ xTlx)-Ba2Cu307 y, Y(Ba 1 xKx)2Cu307 y and YBa2(Cu I xMg~)307 y. In the TI-compound, the results show little effect on T C. In the K-compound, T~ gradually drops with increasing K concentrati
