There is a superconducting article that includes a superconducting film comprising a substrate, one or more buffer layers, and a high temperature superconducting (HTS) layer. The superconducting layer may be comprised of the chemical composition REBaCuO, where RE is one or more rare earth elements, for example: Y, La, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu. The superconductor layer is produced using Photo-Assisted Metal Organic Chemical Vapor Deposition (PAMOCVD) and contains non-superconducting nanoparticles. The nanoparticles are substantially provided in the a-b plane and naturally oriented. The non-superconducting nanoparticles provide flux pinning centers that improve the critical current properties of the superconducting film.

An electric-pulse-induced-resistance change device (EPIR device) is provided which is a resistance switching device. It has a buffer layer inserted between a first active resistance switching layer and a second active resistance switching layer, with both active switching layers connected to electrode layers directly or through additional buffer layers between the active resistance switching layers and the electrodes. This device in its simplest form has the structure: electrode-active layer-buffer layer-active layer-electrode. The second active resistance switching layer may, in the alternative, be an ion donating layer, such that the structure becomes: electrode-active layer-buffer layer-ion donating layer-electrode. The EPIR device is constructed to mitigate the retention challenge.

A switchable resistive device has a multi-layer thin film structure interposed between an upper conductive electrode and a lower conductive electrode. The multi-layer thin film structure comprises a perovskite layer with one buffer layer on one side of the perovskite layer, or a perovskite layer with buffer layers on both sides of the perovskite layer. Reversible resistance changes are induced in the device under applied electrical pulses. The resistance changes of the device are retained after applied electric pulses.
