Field-Free Superconducting Diode in a Magnetically Nanostructured Superconductor
نویسندگان
چکیده
A strong superconducting diode effect (SDE) is revealed in a thin film periodically nanostructured with magnetic dots. The SDE caused by the current-activated dissipation mitigated vortex-antivortex pairs (VAPs), which nucleate under dots, move and annihilate superconductor - eventually driving system to high-resistive state. Inversing polarity of applied current destimulates nucleation VAPs, remains up far larger currents, leading pronounced diodic response. Our dissipative Ginzburg-Landau simulations detail involved processes, provide reliable geometric parametric ranges for experimental realization such non-volatile diode, operates absence any field while being fluxonic design.

Magnetically Controlled Photovoltaic Diode Structure
We propose a new integrated device for spintronics application, which is based on a hybrid metal-semiconductor structure. The device consists of a Si-based p-i-n photodetector sandwiched between two layers of a ferromagnetic metal (3d ferromagnet or half-metallic compound). The photocurrent flowing in such a system is shown to depend on its magnetic configuration. This, in turn, allows controll...
متن کاملMagnetically controlled superconducting weak links
We have designed and characterized a magnetic template which can be switched between chains of parallel and antiparallel field distribution by applying an in-plane magnetic field. The parallel field profile creates highly mobile vortex channels in a superconducting film deposited on top, reproducing the behavior of a weak link as evidenced by the presence of Shapiro steps in the current-voltage...
متن کاملSuperconducting magnetoresistance in ferromagnet/superconductor/ferromagnet trilayers
Magnetoresistance is a multifaceted effect reflecting the diverse transport mechanisms exhibited by different kinds of plain materials and hybrid nanostructures; among other, giant, colossal, and extraordinary magnetoresistance versions exist, with the notation indicative of the intensity. Here we report on the superconducting magnetoresistance observed in ferromagnet/superconductor/ferromagnet...
متن کاملMagnetically induced decrease in droplet contact angle on nanostructured surfaces.
We report a magnetic technique for altering the apparent contact angle of aqueous droplets deposited on a nanostructured surface. Polymeric tubes with embedded superparamagnetic magnetite (Fe(3)O(4)) nanoparticles were prepared via layer-by-layer deposition in the 800 nm diameter pores of polycarbonate track-etched (PCTE) membranes. Etching away the original membrane yields a superparamagnetic ...
