supercurrent

It works as follows: a spin wave generates a magnetic field that in turn generates a supercurrent in the superconductor.

That supercurrent acts as a mirror for the spin wave: the superconducting electrode reflects the magnetic field back to the spin wave.

Recently, researchers have observed nonreciprocal supercurrent transport leading to diode effects in various superconducting materials with different geometric structures and designs, including single crystals, thin films, heterostructures, nanowires, and Josephson junctions.

A superconducting diode enables dissipationless supercurrent to flow in only one direction, and provides new functionalities for superconducting circuits.

Unlike conventional semiconductors and normal conductors, electrons in superconductors constitute pairs, known as Cooper pairs, and the flow of Cooper pairs is called a supercurrent.
