Title: Growth and electrical transport properties of ${La}_{0.7} {Sr}_{0.3} {MnO}_{3}$ thin films on ${Sr}_{2} {IrO}_{4}$ single crystals

Abstract

We report the physical properties of La_0.7Sr_0.3MnO₃ thin films on Sr₂IrO₄ single crystals. The manganite films are deposited using oxide molecular beam epitaxy on flux-grown (001)-oriented iridate crystals. Temperature-dependent magnetotransport and x-ray magnetic circular dichroism measurements reveal the presence of a ferromagnetic metallic ground state in the films, consistent with films grown on SrTiO₃ and La_0.3Sr_0.7Al_0.65Ta_0.35O₃. A parallel resistance model is used to separate conduction effects within the Sr₂IrO₄ substrate and the La_0.7Sr_0.3MnO₃ thin films, revealing that the measured resistance maximum does not correspond to the manganite Curie temperature but results from a convolution of properties of the near-insulating substrate and metallic film. The ability to grow and characterize epitaxial perovskites on Sr₂IrO₄ crystals enables a new route for studying magnetism at oxide interfaces in the presence of strong spin-orbit interactions.

Effect of Sr doping on the magnetic exchange interactions in manganites of type $L a_{1 - x} S r_{x} M n_{y} A_{1 - y} O_{3} (A = Ga, Ti; 0.1 \leq y \leq 1)$

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 .

Persistent Paramagnons Deep in the Metallic Phase of ${Sr}_{2 - x} {La}_{x} {IrO}_{4}$

Journal Article Gretarsson, H. ; Sung, N. H. ; Porras, J. ; ... - Physical Review Letters

We have studied the magnetic excitations of electron-doped Sr_2-xLa_xIrO₄ (0 ≤ x ≤ 0.10) using resonant inelastic x-ray scattering at the Ir L₃ edge. The long-range magnetic order is rapidly lost with increasing x, but two-dimensional short-range order (SRO) and dispersive magnon excitations with nearly undiminished spectral weight persist well into the metallic part of the phase diagram. The magnons in the SRO phase are heavily damped and exhibit anisotropic softening. Their dispersions are well described by a pseudospin-1=2 Heisenberg model with exchange interactions whose spatial range increases with doping. We also find a doping-independent high-energy magnetic continuum, which ismore »« less

Anisotropic antiferromagnetic order in the spin-orbit coupled trigonal-lattice ${Ca}_{2} {Sr}_{2} {IrO}_{6}$

Here, we used single-crystal x-ray and neutron diffraction to investigate the crystal and magnetic structures of trigonal lattice iridate Ca₂Sr₂IrO₆. The crystal structure is determined to be R¯3 with two distinct Ir sites. The system exhibits long-range antiferromagnetic order below T_N = 13.1 K. The magnetic wave vector is identified as (0,0.5,1) with ferromagnetic coupling along the a axis and antiferromagnetic correlation along the b axis. Spins align dominantly within the basal plane along the [1,2,0] direction and tilt 34° toward the c axis. The ordered moment is 0.66(3) μ_B/Ir, larger than other iridates where iridium ions form corner- ormore »« less

Isotropic and anisotropic regimes of the field-dependent spin dynamics in ${Sr}_{2} {IrO}_{4}$ : Raman scattering studies

Journal Article Gim, Y. ; Sethi, A. ; Zhao, Q. ; ... - Physical Review B

A major focus of experimental interest in Sr₂IrO₄ has been to clarify how the magnetic excitations of this strongly spin-orbit coupled system differ from the predictions of an isotropic 2D spin-1/2 Heisenberg model and to explore the extent to which strong spin-orbit coupling affects the magnetic properties of iridates. Here, we present a high-resolution inelastic light (Raman) scattering study of the low energy magnetic excitation spectrum of Sr₂IrO₄ and doped Eu-doped Sr₂IrO₄ as functions of both temperature and applied magnetic field. We show that the high-field (H > 1.5 T) in-plane spin dynamics of Sr₂IrO₄ are isotropic and governed bymore »« less

Strain-induced tetragonal distortions and multiferroic properties in polycrystalline ${Sr}_{1 - x} B a_{x} Mn O_{3}$ ( $x = 0.43 - 0.45$ ) perovskites

Journal Article Somaily, H. ; Kolesnik, S. ; Mais, J. ; ... - Physical Review Materials

Here, we report a comprehensive structure-property phase diagram of unique single-ion type-1 multiferroic pseudocubic Sr_1-xBa_xMnO₃ perovskites. Employing a specially designed multi-step reduction-oxidation synthesis technique, we describe the successful synthesis of previously unknown Sr_1-xBa_xMnO₃ compositions in their polycrystalline form with a significantly extended Ba solubility limit that is only rivaled by a very limited number of crystals and thin films grown under non-equilibrium conditions. Understanding the multiferroic interplay with structure in Sr_1-xBa_xMnO₃ is of great importance as it opens the door wide to the development of newer materials from the parent (AA’)(BB’) O₃ system with enhanced properties. To this end, usingmore »« less
