“…Owing to the novel physical properties and potential applications in advanced electronic and spintronic devices, perovskite manganite with the generic formula of RE 1−x AE x MnO 3 (RE = rare earth, AE = Ca, Sr, Ba, and Pb) has attracted intensive research interests (Wang et al, 2014;Zheng et al, 2019).The strong coupling of spin, charge, orbital, and lattice degrees of freedom results in exotic magnetic and transport properties in perovskite manganite (Zhang et al, 2022;Moshnyaga et al, 2003). For example, colossal magnetoresistance (CMR) has been achieved in doped perovskite manganite, despite the fact that a high magnetic field (several Tesla) is required, which limits its further application (Kang et al, 2012;Wang et al, 2016).…”

The integration of functional oxide thin films on flexible substrates is critical for their application in flexible electronics. Here, to achieve flexible perovskite manganite oxide film with excellent low-field magnetoresistance (LFMR) effect, textured La0.67Sr0.33MnO3 (LSMO):ZnO nanocomposite film was deposited on a flexible mica substrate with ZnO buffer using pulsed laser deposition (PLD). Compared to the polycrystalline LSMO:ZnO nanocomposite film directly deposited on mica without buffer, the LSMO:ZnO/ZnO/mica sample exhibits larger saturation magnetization (164 emu/cm3) and higher Curie temperature (∼319 K), which results from the crystallinity and strain in the LSMO phase. In addition, the LSMO:ZnO/ZnO/mica film presents a high MR value of ∼39% at 10 K under 1 T. Furthermore, the good mechanical stretchability and property stability of the nanocomposite thin films have been demonstrated with mechanical bending.

Magnetic anisotropy plays an important role in the development of manganite-based magnetic devices. Establishing a deeper understanding of the anisotropy in manganites is useful for controlling their magnetic properties. We have studied the structure, lattice strain, and magnetic properties of La0.5Ba0.5MnO3 (LBMO-5) films with the thickness of 12 nm–96 nm, grown on the (001) SrTiO3 (STO) substrate. The LBMO-5 films are grown with high crystalline quality. The orientation relationship between the LBMO-5 film and the STO substrate [(001)f//(001)s, (010)f//(010)s, and (100)f//(100)s] exists at the film/substrate interface. With increasing the thickness of the film to 48 nm, the LBMO-5 film is fully strain relaxed. The LBMO-5 film shows the out-of-plane magnetic anisotropy (OMA) along the three mutually perpendicular crystalline axis directions. Usually, the manganite films with tetragonal distortion show both the OMA and the in-plane magnetic isotropy. However, the in-plane magnetic anisotropy (IMA) along the two mutually perpendicular in-plane directions ([010]f and [100]f) is clearly observed in LBMO-5 films. We attribute this new observation of the IMA to the in-plane structural anisotropy along the two distinct crystalline axes. Our studies provide helpful guidance for the understanding and the tuning of the IMA.
