Abstract

We have fabricated Sm1+xBa2-xCu3Oy (SmBCO) multilayer (Multi-SmBCO) films with alternating main SmBCO (x = 0.04) layers and additional Sm-rich (x = 0.08) layers. We confirmed that Cu2O precipitates in PLD-SmBCO films increased with increasing film thickness, though those in the Multi-SmBCO films hardly appeared even in thick films. Ic of the Multi-SmBCO film with a 1.7 μm thickness achieved 800 A/cm-width (Jc = 4.6 MA/cm2) at 77 K. Furthermore, the Multi-SmBCO film showed improved Jc at all magnetic field, especially, at high-magnetic fields. The enhancement of Jc in the high-magnetic fields would be related to Sm-rich phase (low-Tc phase) formed by introducing the Sm-rich layers.
