Title: Reversible control of magnetism in La_0.67Sr_0.33MnO₃ through chemically-induced oxygen migration

Abstract

We demonstrate reversible control of magnetization and anisotropy in La_0.67Sr_0.33MnO₃ films through interfacial oxygen migration. Gd metal capping layers deposited onto La_0.67Sr_0.33MnO₃ leach oxygen from the film through a solid-state redox reaction to form porous Gd₂O₃. X-ray absorption and polarized neutron reflectometry measurements show Mn valence alterations consistent with high oxygen vacancy concentrations, resulting in suppressed magnetization and increased coercive fields. Effects of the oxygen migration are observed both at the interface and also throughout the majority of a 40 nm thick film, suggesting extensive diffusion of oxygen vacancies. After Gd-capped La_0.67Sr_0.33MnO₃ is exposed to atmospheric oxygen for a prolonged period of time, oxygen diffuses through the Gd₂O₃ layer and the magnetization of the La_0.67Sr_0.33MnO₃ returns to the uncapped value. In conclusion, these findings showcase perovskite heterostructures as ideal candidates for developing functional interfaces through chemically-induced oxygen migration.

Tuning the dead-layer behavior of La{sub 0.67}Sr{sub 0.33}MnO{sub 3}/SrTiO{sub 3} via interfacial engineering

Journal Article Peng, R. ; Xu, H. C. ; Xia, M. ; ... - Applied Physics Letters

The dead-layer behavior, deterioration of the bulk properties in near-interface layers, restricts the applications of many oxide heterostructures. We present the systematic study of the dead-layer in La{sub 0.67}Sr{sub 0.33}MnO{sub 3}/SrTiO{sub 3} grown by ozone-assisted molecular beam epitaxy. Dead-layer behavior is systematically tuned by varying the interfacial doping, while unchanged with varied doping at any other atomic layers. In situ photoemission and low energy electron diffraction measurements suggest intrinsic oxygen vacancies at the surface of ultra-thin La{sub 0.67}Sr{sub 0.33}MnO{sub 3}, which are more concentrated in thinner films. Our results show correlation between interfacial doping, oxygen vacancies, and the dead-layer, whichmore »« less

Orientation Control of Interfacial Magnetism at La_0.67Sr_0.33MnO₃/SrTiO₃ Interfaces

Journal Article Guo, Er-Jia ; Charlton, Timothy ; Ambaye, Haile ; ... - ACS Applied Materials and Interfaces

Understanding the magnetism at the interface between a ferromagnet and an insulator is essential because the commonly posited magnetic “dead” layer close to an interface can be problematic in magnetic tunnel junctions. Previously, degradation of the magnetic interface was attributed to charge discontinuity across the interface. In this paper, the interfacial magnetism was investigated using three identically prepared La_0.67Sr_0.33MnO₃ (LSMO) thin films grown on different oriented SrTiO₃ (STO) substrates by polarized neutron reflectometry. In all cases the magnetization at the LSMO/STO interface is larger than the film bulk. We show that the interfacial magnetization is largest across the LSMO/STO interfacesmore »« less

Evolution of the electronic structure of C{sub 60}/La{sub 0.67}Sr{sub 0.33}MnO{sub 3} interface

Journal Article Xie, Haipeng ; Niu, Dongmei ; Lyu, Lu ; ... - Applied Physics Letters

The evolution of the electronic structure at the interface between fullerene (C{sub 60}) and La{sub 0.67}Sr{sub 0.33}MnO{sub 3} (LSMO) has been investigated with ultraviolet photoemission spectroscopy and X-ray photoemission spectroscopy. There is a 0.61 eV barrier for the electrons to be injected from LSMO to C{sub 60}. The energy bands keep bending upward with increasing C{sub 60} thickness. A total energy bending of 0.72 eV is observed, changing the C{sub 60} film from n-type to p-type. The n-p transition is ascribed to the diffusion of oxygen from LSMO to C{sub 60} which subsequently strips electrons from C{sub 60}, making the latter p-type.more »« less

The synthesis and complex anion-vacancy ordered structure of La{sub 0.33}Sr{sub 0.67}MnO{sub 2.42}

Journal Article Dixon, Edward ; Hadermann, Joke ; Hayward, Michael A., E-mail: michael.hayward@chem.ox.ac.uk - Journal of Solid State Chemistry

The low-temperature topotactic reduction of La{sub 0.33}Sr{sub 0.67}MnO{sub 3} with NaH results in the formation of La{sub 0.33}Sr{sub 0.67}MnO{sub 2.42}. A combination of neutron powder and electron diffraction data show that La{sub 0.33}Sr{sub 0.67}MnO{sub 2.42} adopts a novel anion-vacancy ordered structure with a 6-layer OOTOOT' stacking sequence of the 'octahedral' and tetrahedral layers (Pcmb, a=5.5804(1) A, b=23.4104(7) A, c=11.2441(3) A). A significant concentration of anion vacancies at the anion site, which links neighbouring 'octahedral' layers means that only 25% of the 'octahedral' manganese coordination sites actually have 6-fold MnO{sub 6} coordination, the remainder being MnO{sub 5} square-based pyramidal sites.

Tunnelling anisotropic magnetoresistance at La{sub 0.67}Sr{sub 0.33}MnO{sub 3}-graphene interfaces

Journal Article Phillips, L. C., E-mail: lee.phillips@cantab.net ; Yan, W. ; Kar-Narayan, S. ; ... - Applied Physics Letters

Using ferromagnetic La{sub 0.67}Sr{sub 0.33}MnO{sub 3} electrodes bridged by single-layer graphene, we observe magnetoresistive changes of ∼32–35 MΩ at 5 K. Magneto-optical Kerr effect microscopy at the same temperature reveals that the magnetoresistance arises from in-plane reorientations of electrode magnetization, evidencing tunnelling anisotropic magnetoresistance at the La{sub 0.67}Sr{sub 0.33}MnO{sub 3}-graphene interfaces. Large resistance switching without spin transport through the non-magnetic channel could be attractive for graphene-based magnetic-sensing applications.
