“…23 The appearance of tilted octahedra in the 3-unit-cell-thick LAO film is not surprising since biaxial tension stabilizes in-plane rotations for this particular tilt system. Indeed, rotations were previously observed in LaNiO 3 layers only 1-unit-cell thick in LaNiO 3 /SrMnO 3 superlattices (where bulk LaNiO 3 is a − a − a − and SrMnO 3 exhibits no rotations), 7 but the rotation magnitude was substantially reduced, returning to bulk-like values only after reaching a distance of ∼4 unit cells from the interface, much like the results in Fig. 4(c).…”

Many complex oxides display an array of structural instabilities often tied to altered electronic behavior. For oxide heterostructures, several different interfacial effects can dramatically change the nature of these instabilities. Here, we investigate LaAlO3/SrTiO3 (001) heterostructures using synchrotron x-ray scattering. We find that when cooling from high temperature, LaAlO3 transforms from the \documentclass[12pt]{minimal}\begin{document}$Pm\bar{3}m$\end{document}Pm3¯m to the Imma phase due to strain. Furthermore, the first 4 unit cells of the film adjacent to the substrate exhibit a gradient in rotation angle that can couple with polar displacements in films thinner than that necessary for 2D electron gas formation.

“…Here, the distortions of the B O 6 octahedra at the BMO/ BFO interfaces may be not suitable for optimum magnetic coupling. [25][26][27][28] Similar effects of strongly sensitive magnetic properties to structural distortion have been observed previously in superlattices of [ 25 (SL-LSMO/BTO). Strong enhancements of T C were found in these strained superlattices, 1000 K for SL-LCMO/BTO, and 650 K for SL-LSMO/ BTO, whereas in relaxed bulk and plain thin fi lms of LCMO and LSMO lower T C s of only 250 and 370 K, respectively, were achieved.…”

“…Moreover, the lattice strain from the substrate as well as the superlattice interfaces can affect the magnetic behavior as a result of changes in orbital ordering or bonding distortion of the B O 6 octahedra. [25][26][27][28][29] Here, in SL-BFO m /BMO m ( m = 1, 2, 4, and 8 unit cells (u.c. )), tuning Fe-Mn magnetic interactions through interfacial strain and charge engineering is demonstrated.…”

polarization is very small (0.1 µ C cm −2 at ≈90 K) or it is even paraelectric. [ 4 ] In BFO, strong FE behavior (Ferroelectric transition temperature, T C,FE ≈ 1103 K) coexists together with antiferromagnetism (AFM). BFO has an incommensurate cycloidally modulated G-type AFM structure with a large period of 62 nm (Néel temperature, T N ≈ 650 K). [ 5,6 ] Despite having ferroelectric and magnetic ordering at high temperatures, BFO has drawbacks for practical applications. Most notably the weak FM-like magnetic behavior results from destruction of its incommensurate magnetic structure leading to AFM. [ 6 ] With strong ferromagnetic behavior in BMO and strong ferroelectric behavior in BFO, various studies have suggested combining BMO and BFO in order to achieve room-temperature (RT) multiferroicity. [7][8][9][10] One approach is to modify the local spin confi guration of Fe by chemical doping at the B -site. [ 8,9 ] By 50% doping, this simple concept could result in ordered double perovskite ferrites of Bi 3+ 2 Fe6 (TM = transition metal: Cr, Mn, Co, Ni, and Cu) giving antiferromagnetically coupled high spin state of the TM and Fe. However, this concept has not been widely realized due to the lack of cation ordering as a result of negligible differences in ionic valences and ionic radii. [11][12][13][14][15] On the other hand, disordered double perovskites (notably BiFe 0.5 Mn 0.5 O 3 (BFMO) and Bi 2 CoMnO 6 (BCMO)) show a strongly enhanced T C albeit with lower magnetic moment than expected for the ordered structure. [ 16,17 ] Pálová et al. extended the idea of ordered double perovskites by theoretically studying BFMO with an ordered nanoscale checkerboard structure (NCB-BFO/BMO, see Figure 1 a), i.e., columnar B -site ordering. [ 10 ] Their calculations predict that an ordered NCB-BFO/BMO would be ferroelectric and ferrimagnetic (FiM) with M S of 3.8 µ B /Fe-Mn pair and T C of 406 K, as a result of magnetic ordering arising from the superexchange coupling between the neighboring AFM-Fe and FM-Mn. [ 10 ] Unfortunately, spontaneous columnar B -site ordering is not expected and high quality growth of artifi cial 1:1 BFO/BMO superlattices along the 〈110〉 direction is very hard.

“…For example, the temperature of the metal-to-insulator transition systematically increases across the RNiO 3 series (R ≠ La) with increasing deviation of the Ni-O-Ni bond angle from the ideal 180° angle in the cubic perovskite structure [7]. In thin films, octahedral tilts are modified by epitaxial coherency strains [8][9][10][11][12][13][14][15][16][17]. It is, however, less well understood how (or if) they respond by interfacial coupling to the oxygen octahedral tilts in adjacent layers or the substrate.…”

Structural origins of the properties of rare earth nickelate superlattices

NiO 6 octahedral tilts in the LaNiO 3 /SrTiO 3 superlattices are quantified using position averaged convergent beam electron diffraction in scanning transmission electron microscopy. It is shown that maintaining oxygen octahedra connectivity across the interface controls the octahedral tilts in the LaNiO 3 layers, their lattice parameters and their transport properties.Unlike films and layers that are connected on one side to the substrate, subsequent LaNiO 3 layers in the superlattice exhibit a relaxation of octahedral tilts towards bulk values. This relaxation is facilitated by correlated tilts in SrTiO 3 layers and is correlated with the conductivity enhancement of the LaNiO 3 layers in the superlattices relative to individual films.
