Summary: In this study, we investigated the structural and magnetic properties of Tb(Fe0.2Mn0.2Co0.2Cr0.2Ni0.2)O-3 (T5BO) high-entropy oxide perovskite thin films. By using synchrotron-based x-ray absorption spectroscopy and x-ray magnetic circular dichroism, we performed an element-sensitive study on epitaxial T5BO thin films. The results revealed a magnetic multiphase with variable ferromagnetic ordering, which provides a promising approach for designing ferroic properties in Tb-based HEOP thin films.

Summary: A series of SrRuO3 (SRO) single crystalline thin films were grown on a flexible substrate using pulsed laser deposition technology with a BaTiO3 (BTO) buffer layer. The magnetic properties of the SRO films, including Curie temperature Tc, saturation magnetization Ms, and coercivity Hc, were strongly influenced by the film thickness and the bending state. The control of mechanical bending and variation of film thickness have significant effects on the magnetic properties of the SRO films and their potential application in flexible devices.

Summary: In complex oxides, the exsolution process, modulated by simple doping control, is demonstrated to be an efficient method for achieving tunable magnetism and nanocup morphology in perovskite ferroelectric thin films. Structural and magnetic analyses verify the reinforcement of phase-separated nanocup formation through Co and Fe codoping, resulting in the formation of the CoFe2O4 spinel ferrimagnet. Density functional theory calculations show that different doping combinations change the exsolution energies, leading to the selective formation of nanocup structures. This study presents a simple and effective methodology for engineering nanostructure and multifunctionality in nanocomposite films.

Summary: Defect engineering in perovskite thin films has received extensive attention due to their atomic-level modification and the design of novel nanostructures. However, three-dimensional defect-assisted nanostructures in thin film matrices usually have large misfit strains and unstable structures. In contrast, one- or two-dimensional defect-assisted nanostructures embedded in thin films can sustain large misfit strains without relaxation, making them suitable for defect engineering in perovskite thin films.

Summary: The dynamic structure changes in metal halide perovskite lattice upon photoexcitation and its impact on carrier transport properties in Ruddlesden-Popper phase perovskite thin films are reported in this study. Time-resolved X-ray scattering technique reveals rapid lattice expansion and slow relaxation over 100 ns after photoexcitation. The expansion is attributed to lattice thermal fluctuations caused by photon energy deposition. High laser powers induce strong local structural disorder, increasing the charge dissociation activation energy and leading to localized transport.

Summary: This paper investigates the evaporation and deposition of a perovskite thin liquid film on a hydrophilic substrate, with a focus on the flow patterns within the film and the impact of ultrasonic vibrations on the flow uniformity. The study reveals the mechanics of evaporation and deposition processes in thin liquid films, attributing flow patterns to surface-tension-induced Marangoni flows and ruling out buoyancy-induced convection. Additionally, thermography results show agreement between temperature maps and flow patterns on the film surface, with ultrasonic vibrations enhancing micromixing for more uniform flow patterns.

Summary: The effect of laser irradiation with power ranging from 20 mW to 200 mW on a 109 nm thick Fe51Rh49 film was investigated. The initial A1 structure with paramagnetic magnetic ordering was achieved after irradiation with Ne+ ions. Physical damage to the layer was observed at higher powers, while a well-defined magnetic structure reflecting the laser irradiation pattern was observed at the lowest power. These results have potential applications in laser ablation and fabrication of ferromagnetic patterns in paramagnetic FeRh thin films.

Summary: This study explores the potential of using an organic salt, N,N-dimethylanilinium tetrakis(pentafluorophenyl)borate, as a dopant for Sn-based perovskite devices. The thin film transistors based on the doped 2D/3D perovskite PEAFASnI(3) show remarkable improvement in hole mobility, with a low subthreshold swing, small sweep hysteresis, and exceptional bias stability. The bulky chemical structure of the dopant prevents it from penetrating the perovskite lattice and provides surface passivation against Sn oxidation.

Summary: This study investigates the magnetic behavior of a heterojunction consisting of a ferromagnetic nickel film and an organic semiconductor layer, revealing that the adsorption of the organic semiconductor layer not only reverses the magnetization direction but also enhances the magnetic ordering. It is found that the cyano group in the adsorbed organic semiconductor is spin-polarized and undergoes charge transfer with the nickel layer. Density functional theory calculations suggest that the experimentally observed spin polarization originates from the hybridization between the cyano group's pi orbitals and nickel's d band. These findings highlight the importance of the hybrid states at the organic-ferromagnet interface in tailoring the magnetic behavior.

Summary: Considerable efforts have been made to combine a ferromagnetic layer with a perovskite film in light-controlled spintronic devices. Control over the interface quality and the interaction between the ferromagnetic and perovskite layers is crucial for achieving such combinations. This study proposes the insertion of an ultrathin heterointerface of aluminum oxide or graphene layer to improve the wetting between perovskite and metal films. The results show that a continuous and dense perovskite coating can be achieved without voids, and the coating has a negligible capping effect on magnetism.

Summary: In this study, magnesium (Mg) was added to the palladium (Pd)/ferromagnetic multilayers to enhance and stabilize the effects of hydrogenation. It was found that Mg could absorb hydrogen (H) at room temperature under 1 bar H-2 pressure with the help of a Pd-capping layer. The hydrogenation effect increased the magnetic coercivity and surface roughness, and transformed the crystalline structure from pure Mg to magnesium hydride (MgH2).

Summary: In this study, a hydrogen-sensitive FePd alloy film was deposited on Co/[Pt/Co]4/Pt multilayers with perpendicular magnetic anisotropy (PMA). The spin-reorientation transition (SRT) from perpendicular to in-plane direction was observed in the 2-nm-thick FePd capped multilayer through hydrogenation. Magneto-optic Kerr effect measurements were performed in hydrogen gas at different pressures. Reversible SRT was demonstrated with the cyclic change of H2 pressure. Furthermore, tuning the strength of the PMA multilayer changed the SRT-critical thickness of the FePd cap and the hydrogen-induced SRT behavior, which has potential applications in spintronics.

Summary: This study investigates the effects of Mn1-xPdx-based antiferromagnetic (AFM) thin films on triggering perpendicular magnetic anisotropy (PMA) in ferromagnetic (FM) films. The results demonstrate that Mn1-xPdx films can induce PMA in Co/Ni films with weak in-plane magnetic anisotropy through either interfacial crystalline anisotropy or antiferromagnet-induced exchange coupling. For Co/Fe films with strong in-plane magnetic anisotropy, Mn-rich Mn1-xPdx films can induce stable PMA at low temperatures through enhanced spin-orbit coupling and antiferromagnet-induced exchange coupling. These findings suggest that Mn1-xPdx films are promising for achieving controllable PMA.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
