“…As the temperature increases, the thermal disturbance further enhances the spin disorder, 32 contributing to the increased positive FDMR. This is consistent with the previous report that the non-collinear spin textures can be induced by the strong SOC and interfacial DMI in various heavy metal/oxide heterostructures, such as the Pt/a-Fe 2 O 3 , 12 Pt/CoFe 2 O 4 , 16 Pt/Y 3 Fe 5 O 12 , 33 and perovskite oxides La 0.3 Sr 0.7 MnO 3 /SrIrO 3 34 and SrRuO 3 /SrIrO 3 35,36 heterostructures, SrRuO 3 /SrIrO 3 superlattices. 37 In addition to the enhanced electron scattering induced by the spin disorder, the weak antilocalization (WAL) effect can also cause positive MR in LSMO.…”

“…Some results support the conclusion that THE is due to the chiral magnetic textures such as skyrmions ( Fig. 3 a) in ferromagnetic SrRuO 3 , by studying the temperature-, field- and thickness- dependences of THE with various experimental methods, including magnetotransport and magnetic imaging [ 48 , 52 , 72 , 73 ]. By contrast, other studies imply that the “so-called” THE is probably due to the supposition of AHE signals from two conducting channels of SrRuO 3 that have different signs of AHE as well as different coercivity ( Fig.…”

“…Given the strong SOC in the 5 d transition metal oxides, their interfaces with magnetic oxides provide vivid platforms to explore emergent magnetic phenomena and functionalities that could not be realized in the heterostructures comprised of either 3 d or 4 d complex oxides. Recent research endeavors have been mainly focused on two types of heterostructures, i.e., (ⅰ) the heterostructure of 5 d SrIrO 3 and 4 d SrRuO 3 [45] , [46] , [47] , [48] , [49] , [50] , [51] , [52] , [53] , [54] and (ⅱ) the heterostructure of 5 d SrIrO 3 and 3 d La 1-x Sr x MnO 3 [55] , [56] , [57] , [58] , [59] , [60] , [61] , [62] , [63] , [64] , [65] , [66] , [67] , [68] .…”

“…[18,19] Recent research on SRO heterostructures and superlattices with ultra-thin SRO layer further show remarkable phenomena. Typical examples include the ferroelectric tunable topological Hall effect (THE), [20][21][22][23][24] skyrmion in BaTiO 3 /SrRuO 3 , [9] and spin chirality fluctuation in 2D SRO ferromagnets with perpendicular magnetic anisotropy.

expansion increases the bandwidth and reduces the density of states (DOS) of the Fermi level, however, the strong orbital hybridization between Ru 4d and O 2p of SRO will enhance the DOS, resulting in ferromagnetic interaction and metallicity, and the Curie temperature (T c ) of bulk SRO as high as 160 K. [16,17] SRO also has good electrical conductivity, thermal property, and chemical inertia, and has a high lattice matching degree on a variety of commonly used substrates. [18,19] Recent research on SRO heterostructures and superlattices with ultra-thin SRO layer further show remarkable phenomena. Typical examples include the ferroelectric tunable topological Hall effect (THE), [20][21][22][23][24] skyrmion in BaTiO 3 /SrRuO 3 , [9] and spin chirality fluctuation in 2D SRO ferromagnets with perpendicular magnetic anisotropy. [25] Besides, SRO is also used extensively in the study of anomalous Hall effect (AHE). [8,9,26,27] In SRO, both the AHE and THE of the SRO/STO heterostructure show a strong SRO thickness (t SRO ) dependence. If the thickness is not accurate or uniform, areas with different thicknesses will be superimposed, resulting in an artificial THE signal. [28] Therefore, a layer-by-layer growth mode is desired to precisely regulate the thickness at the unit cell (u.c.) level.However, quite different from many perovskite oxides such as La 2/3 Sr 1/3 MnO 3 , LaCoO 3 , and SrTiO 3 , where a layerby-layer growth mode can persist for even 100 unit cells, the SRO usually quickly transits from layer-by-layer mode into step-flow mode. According to previous studies, when SRO thin film is grown on a TiO 2 -terminated (001) STO substrate, the terminated atomic layer changes from the B-site to the A-site in the first period, [29,30] resulting in the transition from 2D layerby-layer mode to step-flow mode. In step-flow growth mode, the RHEED intensity does not oscillate and remains stable, making the thickness of the films impossible to be intuitively monitored by RHEED. Therefore, it is difficult to accurately control the thickness of superlattices and multilayer films.In this paper, we report the exploration of layer-by-layer growth of SRO. The epitaxial SRO thin films and (SRO n /STO 5 ) 10 superlattices were grown on TiO 2 -terminated (001) STO substrates. The single TiO 2 -terminated (001) STO substrates were obtained through standard buffered oxide etch (BOE) One of the keys to the construction of metal oxide heterostructures is the short characteristic length scale, which requires controlled growth and interface engineering on an atomic level. At present, the growth mode of SrRuO 3 (SRO) thin films grown on TiO 2 -terminated (001) SrTiO 3 (STO) substrates usually transitions from 2D layer-by-layer to step-flow at the first few growth periods, which is not conducive to the construction of superlattices or multilayer films. In this paper, persistent layer-by-layer growth of SRO thin films is demonstrated by regulating the growth conditions. As a result, the thickness can be precisely controlled down to a sing...
