The perovskite La_(2/3)Sr_(1/3)MnO_(3)(LSMO)-based heterostructures have attracted considerable interest for their potential applications in oxide spintronics,topological electronics,and electrocatalysis.This interest originates due to several key properties exhibited by these heterostructures,which include spin-orbit coupling,high-temperature ferromagnetism,high conductivity,and rich oxygen octahedral distortion.This paper provides a systematic and timely review of the magnetic anisotropy progression in LSMO-based heterostructures because it presents opportunities in oxide spintronic applications.First,a description of the current status of LSMO-based heterostructures is provided,followed by an explanation of the motivations for this review.The factors of compressive strain and substrate orientation are then incorporated to manipulate magnetic anisotropy in manganite oxides heterostructures.The third section summarizes the effects of recent interfacial coupling engineering,oxygen octahedral rotation,and symmetry mismatch dependency on magnetic anisotropy in manganite heterostructures.The fourth section examines the electric-field control of magnetic anisotropy in manganite heterostructures,including the ionic-liquid-gating and reversible switching.Finally,a conclusion of the review is presented,along with a summary of future challenges and outlooks in the tuning methods of magnetic anisotropy for applications in highdensity energy-storage magnets.
