Open AccessVan der Waals integration of high-κ perovskite oxides and two-dimensional semiconductors
Two-dimensional semiconductors can be used to build next-generation electronic devices with ultrascaled channel lengths. However, semiconductors need to be integrated with high-quality dielectrics—which are ch...

Spin control in reduced-dimensional chiral perovskites
Hybrid organic–inorganic perovskites exhibit strong spin–orbit coupling1, spin-dependent optical selection rules2,3 and large Rashba splitting4–8. These characteristics make them promising candidates for spintron...

Open AccessAmbipolar ferromagnetism by electrostatic do** of a manganite
Complex-oxide materials exhibit physical properties that involve the interplay of charge and spin degrees of freedom. However, an ambipolar oxide that is able to exhibit both electron-doped and hole-doped ferr...

Open AccessLong-range magnetic coupling across a polar insulating layer
Magnetic interactions in solids are normally mediated by short-range exchange or weak dipole fields. Here we report a magnetic interaction that can propagate over long distances (∼10 nm) across a polar insulat...

Open AccessParallel charge sheets of electron liquid and gas in La0.5Sr0.5TiO3/SrTiO3 heterostructures
We show here a new phenomenon in La0.5Sr0.5TiO3/SrTiO3 (LSTO/STO) heterostructures; that is a coexistence of three-dimensional electron liquid (3DEL) and 2D electron gas (2DEG), separated by an intervening insula...

Manipulating Electronic States at Oxide Interfaces Using Focused Micro X-Rays from Standard Lab Sources
Recently, X-ray illumination, using synchrotron radiation, has been used to manipulate defects, stimulate self-organization, and to probe their structure. Here, we explore a method of defect-engineering low-di...

Open AccessAnalysis of low-field isotropic vortex glass containing vortex groups in YBa2Cu3O7−x thin films visualized by scanning SQUID microscopy
The glass-like vortex distribution in pulsed laser deposited YBa2Cu3O7 − x thin films is observed by scanning superconducting quantum interference device microscopy and analysed for ordering after cooling in magn...

Open AccessAnisotropic two-dimensional electron gas at the LaAlO3/SrTiO3 (110) interface
The observation of a high-mobility two-dimensional electron gas between two insulating complex oxides, especially LaAlO3/SrTiO3, has enhanced the potential of oxides for electronics. The occurrence of this conduc...
