Title: Magnetism and Conductivity Along Structural Domain Walls of SrTiO3

Abstract

Abstract The interface between the oxide insulators LaAlO ₃ and SrTiO ₃ (LAO/STO) hosts a two-dimensional electron gas. The combination of interfacial conductivity and superconductivity at ultra-low temperatures with the physical phenomena of the oxide parent materials has fueled extensive research in the field since its discovery in 2004. Scanning superconducting quantum interference device (SQUID) measurements have shown that structural domain walls, formed below 105 K, modulate the current flow at the interface and recently revealed weak magnetic signals along the same domain structure. Here we use scanning SQUID to investigate the temperature dependence of different electronic properties of the LAO/STO interface. We find correlation between magnetism and conductivity, which are both spatially modulated on the domain structure. This data suggests a possible relation between the populations of electrons participating in each order.

Imaging and tuning polarity at SrTiO₃ domain walls

Journal Article Frenkel, Yiftach ; Haham, Noam ; Shperber, Yishai ; ... - Nature Materials

Electrostatic fields tune the ground state of interfaces between complex oxide materials. Electronic properties, such as conductivity and superconductivity, can be tuned and then used to create and control circuit elements and gate-defined devices. Here in this paper, we show that naturally occurring twin boundaries, with properties that are different from their surrounding bulk, can tune the LaAlO₃/SrTiO₃ interface 2DEG at the nanoscale. In particular, SrTiO₃ domain boundaries have the unusual distinction of remaining highly mobile down to low temperatures, and were recently suggested to be polar. Here we apply localized pressure to an individual SrTiO₃ twin boundary and detectmore »« less

Modulation of Superconducting Transition Temperature in LaAlO{sub 3}/SrTiO{sub 3} by SrTiO{sub 3} Structural Domains

Journal Article Noad, Hilary ; Wittlich, Pascal ; Mannhart, Jochen ; ... - Journal of Superconductivity and Novel Magnetism

The tetragonal domain structure in SrTiO{sub 3} (STO) is known to modulate the normal-state carrier density in LaAlO{sub 3}/SrTiO{sub 3} (LAO/STO) heterostructures, among other electronic properties, but the effect of STO domains on the superconductivity in LAO/STO has not been fully explored. Using a scanning SQUID susceptometer microscope to map the superconducting response as a function of temperature in LAO/STO, we find that the superconducting transition temperature is spatially inhomogeneous and modulated in a pattern that is characteristic of structural domains in the STO.

Non-universal current flow near the metal-insulator transition in an oxide interface

Journal Article Persky, Eylon ; Vardi, Naor ; Monteiro, Ana L. ; ... - Nature Communications

In systems near phase transitions, macroscopic properties often follow algebraic scaling laws, determined by the dimensionality and the underlying symmetries of the system. The emergence of such universal scaling implies that microscopic details are irrelevant. Here, we locally investigate the scaling properties of the metal-insulator transition at the LaAlO₃/SrTiO₃ interface. We show that, by changing the dimensionality and the symmetries of the electronic system, coupling between structural and electronic properties prevents the universal behavior near the transition. By imaging the current flow in the system, we reveal that structural domain boundaries modify the filamentary flow close to the transition point,more »« less

Tuning the Electron Gas at an Oxide Heterointerface via Free Surface Charges

Journal Article Bell, Christopher - Advanced Materials 23, 1744-1747 (2011)

Oxide heterointerfaces are emerging as one of the most exciting materials systems in condensed matter science. One remarkable example is the LaAlO{sub 3}/SrTiO{sub 3} (LAO/STO) interface, a model system in which a highly mobile electron gas forms between two band insulators, exhibiting two dimensional superconductivity and unusual magnetotransport properties. An ideal tool to tune such an electron gas is the electrostatic field effect. In principle, the electrostatic field can be generated by bound charges due to polarization (as in the normal and ferroelectric field effects) or by adding excess free charge. In previous studies, a large modulation of the carriermore »« less
