Title: Structural “ $δ$ Doping” to Control Local Magnetization in Isovalent Oxide Heterostructures

Abstract

Modulation and δ-doping strategies, in which atomically thin layers of charged dopants are precisely deposited within a heterostructure, have played enabling roles in the discovery of new physical behavior in electronic materials. Here, we demonstrate a purely structural “δ-doping” strategy in complex oxide heterostructures, in which atomically thin manganite layers are inserted into an isovalent manganite host, thereby modifying the local rotations of corner-connected MnO6 octahedra. Combining scanning transmission electron microscopy, polarized neutron reflectometry, and density functional theory, we reveal how local magnetic exchange interactions are enhanced within the spatially confined regions of suppressed octahedral rotations. The combined experimental and theoretical results illustrate the potential to utilize noncharge-based approaches to “doping” in order to enhance or suppress functional properties within spatially confined regions of oxide heterostructures.

Emergent ferromagnetism and insulator-metal transition in δ-doped ultrathin ruthenates

Journal Article Ali, Zeeshan ; Saghayezhian, Mohammad ; Wang, Zhen ; ... - npj Quantum Materials

Abstract Heterostructures of complex transition metal oxides are known to induce extraordinary emergent quantum states that arise from broken symmetry and other discontinuities at interfaces. Here we report the emergence of unusual, thickness-dependent properties in ultrathin CaRuO ₃ films by insertion of a single isovalent SrO layer (referred to as δ-doping). While bulk CaRuO ₃ is metallic and nonmagnetic, films thinner than or equal to ~15-unit cells (u.c.) are insulating though still nonmagnetic. However, δ-doping to middle of such CaRuO ₃ films induces an insulator-to-metal transition and unusual ferromagnetism with strong magnetoresistive behavior.

Journal Article Wang, Wei ; Zhang, Jine ; Shen, Xi ; ... - Physical Review B

Perpendicular magnetic anisotropy (PMA) in multilayer thin films promotes the development of spintronic and magnonic research fields. The origin of the PMA deserves a thorough investigation since it contains rich physics related to multiple factors in the heterostructure system. In this report, we study the origin of PMA in La_2/3Sr_1/3 Mn O₃ (LSMO) thin films sandwiched by La_1-xSr_xCoO_3-δ (LSCO) layers grown on SrTiO₃ substrate, using aberration-corrected scanning transmission electron microscopy. Our findings indicate that the lattice and electronic structures of LSMO can be modified through the inhomogeneous strains induced by nanodomains in LSCO layers. Moreover, we infer that the latticemore »« less

Strain-induced majority carrier inversion in ferromagnetic epitaxial $LaCo O_{3 - δ}$ thin films

Journal Article Chaturvedi, Vipul ; Walter, Jeff ; Paul, Arpita ; ... - Physical Review Materials

Tensile-strained LaCoO_3-δ thin films are ferromagnetic, in sharp contrast to the zero-spin bulk, although no clear consensus has emerged as to the origin of this phenomenon. While magnetism has been heavily studied, relatively little attention has been paid to electronic transport, due to the insulating nature of the strain-stabilized ferromagnetic state. Here, structure, magnetism, and transport are studied in epitaxial LaCoO_3-δ films (10–22-nm thick) on various substrates (from 1.4% compressive to 2.5% tensile strain), using synchrotron x-ray diffraction, scanning probe and transmission electron microscopy, magnetometry, polarized neutron reflectometry, resistivity, and Hall effect. High quality, smooth films are obtained, exhibiting superstructuresmore »« less

Twofold symmetry of proximity-induced superconductivity in ${Bi}_{2} {Te}_{3} / {Bi}_{2} {Sr}_{2} {CaCu}_{2} O_{8 + δ}$ heterostructures revealed by scanning tunneling microscopy

Journal Article Wan, Siyuan ; Gu, Qiangqiang ; Li, Huazhou ; ... - Physical Review B

We observe proximity-induced superconductivity in in situ prepared heterostructures constructed by topological insulator Bi₂Te₃ thin films and high-temperature cuprate superconductors Bi₂Sr₂ CaCu₂O_8+δ. The superconducting gap maximum is about 7.6 meV on the surface of Bi₂Te₃ thin films with a thickness of two quintuple layers, and the gap value decreases with an increase in the film thickness. Moreover, the quasiparticle interference data show clear evidence of a twofold symmetric superconducting gap with gap minima along one pair of the principal crystalline axes of Bi₂Te₃. This gap form is consistent with the Δ_4y notation of the topological superconductivity proposed in such systems.more »« less
