Superconductivity

Ferroelectricity woos pairing

Nature Physics volume 13, pages 624–625 (2017)Cite this article

Subjects

Ferroelectricity and superconductivity do not have much in common. Now, a superconducting and a ferroelectric-like state have been found to coexist in a doped perovskite oxide.

Can ferroelectricity and superconductivity occur simultaneously? Can ferroelectricity boost the superconducting critical temperature? Writing in Nature Physics, Carl Rischau and colleagues1 report experimental results suggesting that the coexistence of a ferroelectric-like state and superconductivity may be possible.
