Electrodeposition and superconductivity of rhenium-iron alloy films from water-in-salt electrolytes

Electrochemical deposition of rhenium-iron alloy from water-in-salt electrolytes containing a super-high concentration lithium chloride is investigated. Different techniques, including cyclic voltammetry, chronoamperometry, X-ray fluorescence, scanning electron microscope, X-Ray diffraction, and electrical measurements at cryogenic temperature are used to characterize the electrochemical system deposited films. The catalytic effect iron on rhenium observed, where rate significantly increases in presence iron. Alloying with inhibits recrystallization as-deposited amorphous At same time, it also greatly suppresses superconductivity rhenium.
