TL;DR: This work reports on superconductivity in the electron gas formed at the interface between two insulating dielectric perovskite oxides, LaAlO3 and SrTiO3.
Journal ArticleDOI
Emergent phenomena at oxide interfaces
TL;DR: Recent technical advances in the atomic-scale synthesis of oxide heterostructures have provided a fertile new ground for creating novel states at their interfaces, with characteristic feature is the reconstruction of the charge, spin and orbital states at interfaces on the nanometre scale.

TL;DR: The electrostatic tuning of the carrier density allows an on/off switching of superconductivity and drives a quantum phase transition between a two-dimensional superconducting state and an insulating state, which opens the way to the development of new mesoscopicsuperconducting circuits.

TL;DR: Electric-field-induced superconductivity in an insulator is reported by using an electric-double-layer gating in an organic electrolyte using a pristine SrTiO(3) single-crystal channel, indicating this method as promising for searching for unprecedented superconducting states.

Journal ArticleDOI
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.

Resistance Minimum in Dilute Magnetic Alloys
TL;DR: In this article, the scattering probability of conduction electrons to the second Born approximatism was calculated based on the s-d interaction model for dilute magnetic alloys, and it was shown that J should be negative in alloys which show a resistance minimum.

Indirect exchange coupling of nuclear magnetic moments by conduction electrons
M. A. Ruderman,C. Kittel +1 more
TL;DR: In this paper, a calculation of the indirect exchange type coupling of nuclear magnetic moments in a metal by means of the hyperfine interaction with the conduction electrons was given, which appears to account qualitatively for the broad nuclear spin resonance lines observed in natural metallic silver.

TL;DR: In this article, it was shown that the magnetoresistive response increases dramatically when the Curie temperature (T C) is reduced, and that the massive magnetoresistance in low-T C systems can be explained by percolative transport through the ferromagnetic domains; this depends sensitively on the relative spin orientation of adjacent magnetoric domains which can be controlled by applied magnetic fields.
