Title: Enhanced magnetism in lightly doped manganite heterostructures: strain or stoichiometry?

Abstract

Lattice mismatch induced epitaxial strain has been widely used to tune functional properties in complex oxide heterostructures. Apart from the epitaxial strain, a large lattice mismatch also produces other effects including modulations in microstructure and stoichiometry. However, it is challenging to distinguish the impact of these effects from the strain contribution to thin film properties. Here, we use La_0.9Sr_0.1MnO₃ (LSMO), a lightly doped manganite close to the vertical phase boundary, as a model system to demonstrate that both epitaxial strain and cation stoichiometry induced by strain relaxation contribute to functionality tuning. The thinner LSMO films are metallic with a greatly enhanced T_C which is 97 K higher than the bulk value. Such anomalies in T_C and transport cannot be fully explained by the epitaxial strain alone. Detailed microstructure analysis indicates La deficiency in thinner films and twin domains formation in thicker films. Our results have revealed that both epitaxial strain and strain relaxation induced stoichiometry/microstructure modulations contribute to the modified functional properties in lightly doped manganite perovskite thin films.

Symmetry mismatch controlled ferroelastic domain ordering and the functional properties of manganite films on cubic miscut substrates

Journal Article Paudel, Binod ; Kang, Kyeong Tae ; Sharma, Yogesh ; ... - Physical Chemistry Chemical Physics. PCCP

We have studied the magnetotransport properties and strain release mechanisms in ferroelastic La_0.9Sr_0.1MnO₃ (LSMO) epitaxial thin films on SrTiO₃ (STO)(001) substrates with different miscut angles. The substrate miscut angle plays a critical role in releasing shear strain and has a huge impact on the properties of the films. The strain relaxes by monoclinic distortion for films on low miscut substrates and for higher miscut substrates, the strain relaxation causes the formation of periodic twin domains with larger periodicities. Furthermore, we observe that the Curie temperature (T_C) decreases systematically, and magnetoresistance (MR) increases with increasing the miscut angle. Such changes inmore »« less

Anisotropic domains and antiferrodistortive-transition controlled magnetization in epitaxial manganite films on vicinal SrTiO₃ substrates

Journal Article Paudel, Binod ; Zhang, Bruce ; Sharma, Yogesh ; ... - Applied Physics Letters

We studied the microstructural evolution and magnetism of ferroelastic La_0.9Sr_0.1MnO₃ (LSMO) epitaxial thin films grown on SrTiO₃ (001) substrates with different miscut angles. The substrate miscut angle plays a critical role in controlling the in-plane magnetic anisotropy. The microscopic origin of such magnetic anisotropy is attributed to the formation of anisotropic stripe domains along the surface step terraces. The magnetization in the LSMO films was found to be selectively modulated by the antiferrodistortive phase transition of the SrTiO₃ substrate. This phenomenon has been qualitatively explained by a strain modified Stoner–Wohlfarth model. We conclude that the magnetization modulation by the SrTiO₃more »« less

Magnetotransport characteristics of strained La{sub 0.7}Sr{sub 0.3}MnO{sub 3} epitaxial manganite films

Journal Article Ovsyannikov, G. A., E-mail: gena@hitech.cplire.ru ; Petrzhik, A M ; Borisenko, I V ; ... - Journal of Experimental and Theoretical Physics

The electrical and magnetic characteristics of La{sub 0.7}Sr{sub 0.3}MnO{sub 3} (LSMO) epitaxial manganite films are investigated by different methods under conditions when the crystal structure is strongly strained as a result of mismatch between the lattice parameters of the LSMO crystal and the substrate. Substrates with lattice parameters larger and smaller than the nominal lattice parameter of the LSMO crystal are used in experiments. It is shown that the behavior of the temperature dependence of the electrical resistance for the films in the low-temperature range does not depend on the strain of the film and agrees well with the resultsmore »« less

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.

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
