Title: Out-of-plane magnetic anisotropy enhancement in $L a_{1 - x} S r_{x} Co O_{3 - δ} / L a_{2 / 3} S r_{1 / 3} Mn O_{3} / L a_{1 - x} S r_{x} Co O_{3 - δ}$ thin films

Abstract

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 lattice distortion in LSCO at low temperatures is a driving force to reorient the spin moment from in-plane direction to out-of-plane direction in LSMO, which could be the nature of the PMA formation. The symmetry breaking in the LSMO layer induced by the domains from LSCO enhances magnetic anisotropy energy in LSMO.

Influence of chemical composition and crystallographic orientation on the interfacial magnetism in $BiFe O_{3}$ / $L a_{1 - x} S r_{x} Mn O_{3}$ superlattices

Journal Article Guo, Er-Jia ; Roldan, Manuel A. ; Sang, Xiahan ; ... - Physical Review Materials

The emergence of magnetism unique to the interface between the multiferroic BiFeO₃ (BFO) and ferromagnetic La_1-xSr_xMnO₃ (LSMO) offers an opportunity to control magnetism in nanoscale heterostructures with electric fields. Here, we investigate the influence of chemical composition and crystallographic orientation on the interfacial magnetism of BFO/LSMO superlattices. Our results reveal that the induced net magnetic moment in the BFO layers increases monotonically with increasing saturation magnetization of the LSMO layers. For the (100)-BFO/LSMO (x=0.2) superlattice, the induced moment reaches a record high value of ~2.8μ_B/Fe. No interfacial magnetization is observed at the (100)-BFO/LSMO interface when LSMO is an antiferromagnet. Inmore »« less

Electrical-current-induced magnetic hysteresis in self-assembled vertically aligned $L a_{2 / 3} S r_{1 / 3} Mn O_{3} : ZnO$ nanopillar composites

Magnetoresistive random-access memory (MRAM) is poised to become a next-generation information storage device. Yet, many materials challenges remain unsolved before it can become a widely used memory storage solution. Among them, an urgent need is to identify a material system that is suitable for downscaling and is compatible with low-power logic applications. Self-assembled, vertically aligned La_2/3Sr_1/3MnO₃: ZnO nanocomposites, in which La_2/3Sr_1/3MnO₃ (LSMO) matrix and ZnO nanopillars form an intertwined structure with coincident-site-matched growth occurring between the LSMO and ZnO vertical interfaces, may offer new MRAM applications by combining their superior electric, magnetic ( B ), and optical properties.

Journal Article Furrer, Albert ; Podlesnyak, Andrey A. ; Pomjakushina, Ekaterina ; ... - Physical Review B

Strontium doping transforms manganites of type La _{1 - x} Sr _x Mn O ₃ from an insulating antiferromagnet ( x = 0 ) to a metallic ferromagnet ( x > 0.16 ) due to the induced charge carriers (holes). We employed neutron scattering experiments in order to investigate the effect of Sr doping on a tailor-made compound of composition La _0.7 S r _0.3 M n _0.1 Ti _0.3 G a _0.6 O ₃ .

Ion-gel-gating-induced oxygen vacancy formation in epitaxial $L a_{0.5} S r_{0.5} Co O_{3 - δ}$ films from in operando x-ray and neutron scattering

Journal Article Walter, Jeff ; Yu, Guichuan ; Yu, Biqiong ; ... - Physical Review Materials

Ionic-liquid/gel-based transistors have emerged as a potentially ideal means to accumulate high charge-carrier densities at the surfaces of materials such as oxides, enabling control over electronic phase transitions. Substantial gaps remain in the understanding of gating mechanisms, however, particularly with respect to charge carrier vs oxygen defect creation, one contributing factor being the dearth of experimental probes beyond electronic transport. Here we demonstrate the use of synchrotron hard x-ray diffraction and polarized neutron reflectometry as in operando probes of ion-gel transistors based on ferromagnetic La_0.5Sr_0.5CoO_3-δ. An asymmetric gate-bias response is confirmed to derive from electrostatic hole accumulation at negative gatemore »« less

Surface and interface properties of $L a_{2 / 3} S r_{1 / 3} Mn O_{3}$ thin films on ${SrTiO}_{3}$ (001)

Journal Article Chen, Lina ; Wang, Zhen ; Wang, Gaomin ; ... - Physical Review Materials

Understanding and manipulating properties emerging at a surface or an interface require a thorough knowledge of structure-property relationships. We report a study of a prototype oxide system, La_2/3Sr_1/3MnO₃ grown on SrTiO₃(001), by combining in situ angle-resolved x-ray photoelectron spectroscopy, ex situ x-ray diffraction, and scanning transmission electron microscopy/spectroscopy with electric transport measurements. We find that La_2/3Sr_1/3MnO₃ films thicker than 20 unit cells (u.c.) exhibit a universal behavior with no more than one u.c. intermixing at the interface but at least 3 u.c. of Sr segregation near the surface, which is (La/Sr)O terminated.
