Dome-shape superconductivity phase diagram can commonly be observed in cuprateand iron-based systems via tuning parameters such as charge carrier doping, pressure, bond angle, and etc. We report doping electrons from transition-metal elements (TM = Co, Ni) substitution can induce high-Tc superconductivity around 35 K in Ca0.94La0.06Fe2As2, which emerges abruptly before the total suppression of ...

We report remarkable photovoltaic effect in YBa2Cu3O6.96 (YBCO) ceramic between 50 and 300 K induced by blue-laser illumination, which is directly related to the superconductivity of YBCO and the YBCO-metallic electrode interface. There is a polarity reversal for the open circuit voltage Voc and short circuit current Isc when YBCO undergoes a transition from superconducting to resistive state. ...

Proximity effects in structures with helimagnetic ordering are investigated. Structures sharp boundaries were prepared by magnetron sputtering. Results indicating a change the magnetic state of helimagnet under influence superconductivity obtained polarized neutron reflectometry. A new type structure alternating layers superconductor and rare-earth is proposed for studying proximity effects. Th...

The critical current of a superconductor can depend on the direction flow due to magnetochiral anisotropy when both inversion and time-reversal symmetry are broken, an effect known as superconducting (SC) diode effect. Here, we consider one-dimensional (1D) systems in which superconductivity is induced via proximity In topological insulator Rashba nanowires, SC magnetic field applied along spin...

Graphene provides a ideal 2D gas of Dirac Fermions which is directly exposed to the environment. Therefore it provides an ideal platform on which to tune, via application of an electrostatic gate, the coupling between electronically ordered adsorbates deposited on its surface. This situation is particularly interesting when the network of adsorbates can induce some electronic order within the u...

Typically, topological superconductivity is reachable via proximity effect by a direct deposition of superconductor (S) on top insulator (TI) surface. Here we observed and analyzed the double critical current in Josephson junctions based fabricated planar Superconducting Quantum Interference Device. By measuring currents as function temperature magnetic field, show that second stems from intrin...

Motivated by recent experiments searching for Majorana zero modes in tripartite semiconductor nanowires with epitaxial superconductor and ferromagnetic-insulator layers, we explore the emergence of topological superconductivity such devices paradigmatic arrangements three constituents. Accounting competition between magnetism superconductivity, treat self consistently describe electronic proper...
