Journal ArticleDOI
Electron pairing without superconductivity
Guanglei Cheng,Michelle Tomczyk,Shicheng Lu,Joshua P. Veazey,Joshua P. Veazey,Mengchen Huang,Patrick Irvin,Sangwoo Ryu,Hyungwoo Lee,Chang-Beom Eom,C. Stephen Hellberg,Jeremy Levy +11 more
TL;DR: Cheng et al. as discussed by the authors showed that electron pairing in strontium titanate (SrTiO3) is stable at temperatures as high as 900 millikelvin, well above the superconducting transition temperature.
Journal ArticleDOI
Room-temperature electronically-controlled ferromagnetism at the LaAlO 3 /SrTiO 3 interface
Feng Bi,Mengchen Huang,Sangwoo Ryu,Hyungwoo Lee,Chung Wung Bark,Chang-Beom Eom,Patrick Irvin,Jeremy Levy +7 more
TL;DR: In this article, the magnetism at the interface between LaAlO3/SrTiO3 and its dependency on charge carriers was studied using magnetic force microscopy, which can be controlled through parameters such as carrier density.

Journal Article
Room-Temperature Electronically-Controlled Ferromagnetism at the LaAlO$_3$/SrTiO$_3$ Interface
TL;DR: Using electrical top gating to control the electron density at the oxide interface, magnetic force microscopy is employed to observe the emergence of an in-plane ferromagnetic phase as electrons are depleted from the interface.
Journal ArticleDOI
Giant conductivity switching of LaAlO3/SrTiO3 heterointerfaces governed by surface protonation.

TL;DR: A fully reversible >4 order of magnitude conductance change is demonstrated at LaAlO3/SrTiO3 (LAO/STO) interfaces, regulated by LAO surface protonation, with far-reaching implications for reconfigurable oxide nanoelectronics and the possibility of novel applications in which electronic properties of these materials can be locally tuned using synthetic chemistry.
