“…In fact, tuning the spin-state of Ru is very promising for spintronics applications of SRO-based heterostructures. Currently, the spin-state modulation in SRO can be mainly achieved by charge transfer or orbital reconstruction [107,108]. In addition, spin-state modulation in SRO can also be achieved by lattice distortions by ( 111)-STO substrate [109,110] and dualferroelectric interface [86,87].…”

SrRuO3 (SRO)-based heterostructures have attracted much attention for potential applications such as electrodes, oxide spintronics, topological electronics and electrocatalytic function mainly due to the strong spin-orbit coupling, itinerant ferromagnetism with 4d electrons, high metallic conductivity, perpendicular magnetic anisotropy and rich oxygen octahedral distortion of SRO. Here, this work aims to offer a timely and systematic review on SRO-based heterostructures for its emerging opportunities in oxide spintronic and topological electronic applications. We first present a brief summary of the current status in SRO-based heterostructures and describe the motivations of this review. We then briefly review the surface and interface modulation in SRO-based heterostructures, including oxygen octahedral distortions (antiferrodistortive mode and ferroelectric mode) engineering and ion defect engineering. In the third part, we discuss the spin-charge interconversion phenomena in SRO-based heterostructures, covering the inverse spin Hall effect and current-induced spin-orbit torques. Particularly, in the fourth part, we discuss the emergent topological Hall effect and underlying mechanism in SRO-based heterostructures, including the two-channel anomalous Hall effect and Berry phase manipulation. The fifth part presents the magnetic Weyl fermions and its electric-field control of SRO films. We finally conclude with a discussion of challenges and prospects of SRO-based heterostructures, which provides a guidance for exploring novel physical properties and designing multifunctional devices based on SRO.

Unexpected, yet useful functionalities emerge when two or more materials merge coherently. Artificial oxide superlattices realize atomic and crystal structures that are not available in nature, thus providing controllable correlated quantum phenomena. This review focuses on 4d and 5d perovskite oxide superlattices, in which the spin–orbit coupling plays a significant role compared with conventional 3d oxide superlattices. Modulations in crystal structures with octahedral distortion, phonon engineering, electronic structures, spin orderings, and dimensionality control are discussed for 4d oxide superlattices. Atomic and magnetic structures, Jeff = 1/2 pseudospin and charge fluctuations, and the integration of topology and correlation are discussed for 5d oxide superlattices. This review provides insights into how correlated quantum phenomena arise from the deliberate design of superlattice structures that give birth to novel functionalities.

The results of a study on the electronic states and valence band offset (VBO) in heterostructures of the transition metal oxide LaNiO3 (LNO)/SrRuO3 (SRO) grown on (001) SrTiO3 (STO) substrates are reported. X‐ray photoelectron spectroscopy (XPS) data reveal the presence of Ni2+ states in LNO layer that can develop a reduced bandwidth of O‐2p and Ni‐3d. Further analysis of XPS data confirms the presence of a VBO, and the value of VBO is found to be +0.02 eV and –0.38 eV for the bilayers of STO/LaNiO3/SrRuO3 (BL‐1) and STO/SrRuO3/LaNiO3 (BL‐2), respectively. Distinct signs of VBO are noticed between the bilayers due to the relative shift of the valence band of the top layer with respect to the bottom layer. Such band shifts can lead to the charge transfer across the (3d−4d) interface, which significantly modifies the global electronic transport and magnetic properties of the bilayers. A detailed discussion on the underlying physical phenomena of electrical transport and magnetic responses triggered by the interface is also incorporated herein.
