Coexistence of magnetic order and two-dimensional superconductivity at LaAlO3/SrTiO3 interfaces
TLDR
The authors showed that Lanthanum aluminate and strontium titanate are insulators, but when they bring them together, the interface between them becomes a two-dimensional superconductor.Abstract:
Lanthanum aluminate and strontium titanate are insulators, but when you bring them together, the interface between them becomes a two-dimensional superconductor. Even more surprising, magnetometry and transport measurements show that this superconducting state coexists with magnetic order.read more

A high-mobility electron gas at the LaAlO3/SrTiO3 heterointerface
TL;DR: A model interface is examined between two insulating perovskite oxides—LaAlO3 and SrTiO3—in which the termination layer at the interface is controlled on an atomic scale, presenting a broad opportunity to tailor low-dimensional charge states by atomically engineered oxide heteroepitaxy.

Superconductivity in a Strong Spin-Exchange Field
Peter Fulde,Richard A. Ferrell +1 more
TL;DR: In this paper, it was shown that the depaired state has a spatially dependent complex Gorkov field, corresponding to a nonzero pairing momentum in the BCS model, and that the presence of the "normal" electrons from the broken pairs reduces the total current to zero, gives the deblating state some spin polarization, and results in almost normal Sommerfeld specific heat and single-electron tunneling characteristics.
