Title: Tuning interfacial exchange interactions via electronic reconstruction in transition-metal oxide heterostructures

Abstract

The impact of interfacial electronic reconstruction on the magnetic characteristics of La 0.7 Sr 0.3 CoO 3 (LSCO)/La 0.7 Sr 0.3 MnO 3 (LSMO) heterostructures was investigated as a function of layer thickness using a combination of soft x-ray magnetic spectroscopy and bulk magnetometry. We found that the magnetic properties of the LSCO layers are impacted by two competing electronic interactions occurring at the LSCO/substrate and LSMO/LSCO interfaces. For thin LSCO layers ( < 5 nm), the heterostructures exist in a highly coupled state where the chemically distinct layers behave as a single magnetic compound with magnetically active Co 2+ ions. As the LSCO thickness increases, a high coercivity LSCO layer develops which biases a low coercivity layer, which is composed not only of the LSMO layer but also an interfacial LSCO layer. These results suggest an intriguing route to tune the magnetic properties of transition metal oxide heterostructures through careful control of the interface structure.

Interface-driven magnetic anisotropy in relaxed La_0.7Sr_0.3CrO₃/La_0.7Sr_0.3MnO₃ heterostructures on MgO

Journal Article Koohfar, Sanaz ; Ozbek, Yasemin ; Bland, Hayden ; ... - Journal of Applied Physics

We investigate the structural and magnetic properties of La_0.7Sr_0.3CrO₃/La_0.7Sr_0.3MnO₃ (LSMO) heterostructures grown on (001)-oriented MgO by molecular beam epitaxy. Due to the large film-substrate lattice mismatch, strain relaxation is found to occur within the first 2–3 unit cells (uc) of the film as evidenced by reflection high energy electron diffraction and high-resolution synchrotron x-ray reciprocal space mapping. Furthermore, we find that the presence of the LSCO spacer and capping layers leads to ferromagnetism in ultra-thin LSMO layers with thicknesses of the order of 2 uc with the magnetic easy axis oriented in the film plane.

Tuning In-Plane Magnetic Anisotropy and Interfacial Exchange Coupling in Epitaxial La_2/3Sr_1/3CoO₃/La_2/3Sr_1/3MnO₃ Heterostructures

Journal Article Feng, Mingzhen ; Ahlm, Nolan ; Sasaki, Dayne Y. ; ... - ACS Applied Materials and Interfaces

Controlling the in-plane magnetocrystalline anisotropy and interfacial exchange coupling between ferromagnetic (FM) layers plays a key role in next-generation spintronic and magnetic memory devices. In this work, we explored the effect of tuning the magnetocrystalline anisotropy of La_2/3Sr_1/3CoO₃ (LSCO) and La_2/3Sr_1/3MnO₃ (LSMO) layers and the corresponding effect on interfacial exchange coupling by adjusting the thickness of the LSCO layer (t_LSCO). The epitaxial LSCO/LSMO bilayers were grown on (110)_o-oriented NdGaO₃ (NGO) substrates with a fixed LSMO (top layer) thickness of 6 nm and LSCO (bottom layer) thicknesses varying from 1 to 10 nm. Despite the small difference (~0.2%) in lattice mismatchmore »« less

Controlling Magnetization Vector Depth Profiles of La_0.7Sr_0.3CoO₃/La_0.7Sr_0.3MnO₃ Exchange Spring Bilayers via Interface Reconstruction

Journal Article Kane, Alexander M. ; Chiu, I-Ting ; Ahlm, Nolan J. ; ... - ACS Applied Materials and Interfaces

The La_0.7Sr_0.3CoO_3-δ/La_0.7Sr_0.3MnO_3-δ (LSCO/LSMO) bilayer system is an ideal perovskite oxide platform for investigating interface reconstruction and its effect on their magnetic properties. Previous studies have shown that LSCO can separate into magnetic sublayers, which possess distinct trends as the total LSCO thickness increases. In this study, we used polarized neutron reflectometry to quantify changes in the magnetic and chemical depth profiles, and it confirms the formation of ~12 Å-thick interfacial LSCO and LSMO layers, characterized by a decreased nuclear scattering length density compared to the bulk of the layers. This decrease is attributed to the combined effects of oxygen vacancymore »« less

Magnetic order and interfacial coupling in oxide thin films and heterostructures probed with soft x-ray dichroism

Conference Arenholz, Elke ; van der Laan, G

The combination of novel magnetic properties induced by reduced dimensionality and strong magnetic interactions across interfaces leads to intriguing new properties in magnetic hetero- and nanostructures not observed in the constituent materials in bulk form. It is the careful optimization of the characteristics of the individual layers as well as the magnetic coupling across the interface that allows us to control the magnetic properties and tailor them for devices, e.g., in information storage and processing technology. Soft x-ray magnetic spectroscopies can make unique contributions to improving our understanding of complex magnetic nanostructures since these techniques provide elemental, valence- and site-symmetrymore »« less

The ultra thin ferroelectric PbZr{sub 0.52}Ti{sub 0.48}O{sub 3} (PZT) films with various thicknesses ranging from 100 (P100) to 10 (P10) nm were grown on La{sub 0.67}Sr{sub 0.33}MnO{sub 3}/(LaAlO{sub 3}){sub 0.3}(Sr{sub 2}AlTaO{sub 6}){sub 0.7} (LSMO/LSAT) (001) substrates deposited by pulsed laser deposition technique. The x-ray diffraction patterns of the heterostructures show only (00l) (l = 1 and/or 2) reflections corresponding to the LSAT substrate, PZT, and LSMO layers. The atomic force microscopy studies show that the root mean square surface roughnesses of P100 and P10 films are 2.39 and 0.99 nm, respectively.
