Abstract

Pr_yBa_2−yCu₃O_x thin films have been synthesized by MOCVD with differents compositions on MgO (100), SrTiO₃ (100), LaAlO₃ (012) substrates. The resistivity of this oxide varies with the composition. This characteristic should allow to modify multilayer properties. Secondary neutron mass spectrometry reveals that little interdiffusion takes place at the interfaces of YBCO / PBCO stacked layers. YBa₂Cu₃O_7−x/PrBa₂Cu₃O_7−x superlattices have been grown by this technique on (100) SrTiO₃. Satellite peaks have been observed in the X-ray diffraction spectrum.

Field modulated microwave absorption and irreversibility line in YBa<inf>2</inf>Cu<inf>3</inf>O<inf>7</inf>/PrBa<inf>2</inf>Cu<inf>3</inf>O <inf>7</inf> multilayers

We describe field modulated microwave absorption measurements in two series of $YBa_{2} Cu_{3} O_{7} PrBa_{2} Cu_{3} O_{7}$ multilayers: those with PrBa₂Cu₃O₇ thickness in the range ∼2.5 to ∼10 nm and with a fixed YBa₂Cu₃O₇ thickness of ∼10 nm and those with different resistivities of the PrBa₂Cu₃O₇ barrier with the same thickness of ∼2.5 nm for YBa₂Cu₃O₇ and PrBa₂Cu₃O₇ layers. The Fourier spectrum of the reflected microwave power reveals one fundamental frequency which appears at T_c and even harmonics of the modulation field frequency f at lower temperatures. The determination of the irreversibility line near T_c inferred from the vanishing of the nonlinear response signal at 2f in the presence of superimposed d.c. and modulation fields is reported. A comparison with results obtained on YBa₂Cu₃O₇ thin films is also given.
