The exchange bias (EB) effect plays a pivotal role in spintronic devices and is governed by the interfacial spin configurations between ferromagnetic (FM) and antiferromagnetic (AFM) layers, but the underlying mechanism is still unveiled. While most progress has been made in understanding longitudinal exchange bias (LEB) in FM/AFM systems, studies on perpendicular exchange bias (PEB) remain limited. In this study, we investigated the EB effects in Mn3-xCoxGa/Mn3Ga bilayers, composed of ferrimagnetic (FI) Mn3-xCoxGa and AFM Mn3Ga layers, offering tunable magnetic anisotropy and interfacial spin configurations. Mn3-xCoxGa exhibits a transition from a hard FI phase with perpendicular magnetic anisotropy (x = 0.12) to a soft FI phase with in-plane magnetic anisotropy (x = 0.57). The spin configuration of Mn3Ga layer is further manipulated through field-cooling direction. This approach enabled a comparative study of LEB and PEB effects. The EB effect was most pronounced in orthogonal spin configurations at the interfaces: PEB for x = 0.12 under an in-plane field and LEB for x = 0.57 under an out-of-plane field. These results provide critical insights into the role of interfacial spin configurations in the EB effect to advance the understanding of EB mechanisms in magnetic multilayers.

Sulfur-containing fossil fuels have driven several environmental concerns that lead to the development of efficient and green desulfurization technologies. Herein, we report the rational design and synthesis of a novel S-scheme p-n heterojunction photocatalyst composed of p-type cobalt ferrite (CoFe2O4) nanoparticles decorated on n-type hierarchical barium zirconate (BaZrO3) perovskite nanocrystals. These nanocomposites were fabricated via a facile sol-gel method followed by a simple impregnation-calcination route, ensuring an intimate interfacial connection. The comprehensive analysis indicates the impact of CoFe2O4 on the structural, optical, and photoactivity of BaZrO3.The resulting CoFe2O4 /BaZrO3 nanocomposites exhibited outstanding visible-light-driven photocatalytic oxidative desulfurization (PODS) of thiophene (C4H4S). The optimal 15 wt.% CoFe2O4 /BaZrO3 heterostructure achieved complete desulfurization efficiency within 150 min at an adjustable dose of 2.0 gL–1, with an apparent reaction rate constant (0.0163 min–1) that is almost 20 times higher than that of pristine BaZrO3. Furthermore, the catalyst demonstrated excellent stability and reusability over five cycles, facilitated by its intrinsic magnetic nature, which allows for effortless recovery. The remarkable photocatalytic enhancement is attributed to the formation of a p-n S-scheme heterojunction, which creates a highly efficient charge separation pathway. A detailed S-scheme charge transfer mechanism for the PODS of C4H4S is proposed.
含硫化石燃料引发了一些环境问题，导致高效和绿色脱硫技术的发展。本文报道了一种新型S-scheme p-n异质结光催化剂的合理设计和合成，该催化剂由p型钴铁氧体（CoFe2O4）纳米颗粒装饰在n型分层锆酸钡（BaZrO3）钙钛矿纳米晶体上组成。这些纳米复合材料是通过简单的溶胶-凝胶法和简单的浸渍-煅烧路线制备的，确保了紧密的界面连接。综合分析表明，CoFe2O4对BaZrO3的结构、光学和光活性都有影响。制备的CoFe2O4 /BaZrO3纳米复合材料对噻吩（C4H4S）具有良好的可见光催化氧化脱硫性能。最佳的CoFe2O4 /BaZrO3异质结构为15 wt.%，在2.0 ml - 1的可调剂量下，可在150 min内实现完全脱硫，表观反应速率常数为0.0163 min - 1，比原始BaZrO3高出近20倍。此外，该催化剂在5个循环中表现出优异的稳定性和可重复使用性，这得益于其固有的磁性，可以轻松回收。显著的光催化增强归因于p-n -s方案异质结的形成，这创造了一个高效的电荷分离途径。提出了C4H4S pod的S-scheme电荷转移机理。

Mn2+ emerges as a promising activator in scintillators due to its high luminescent efficiency and tunable broadband emission. However, exploring Mn2+-doped glass scintillators with high thermal stability remains a significant challenge. Mn2+-doped oxyfluoride glass scintillators with exceptional thermal stability and superior scintillating properties are designed in this paper. Firstly, oxyfluoride glass is adopted as glass host, which possesses the advantages of high transparency, excellent physiochemical stability, and low phonon energy. Secondly, the oxidation of Mn2+ is efficiently suppressed by introducing reducing agent Al. The X-ray excited luminescence (XEL) intensity of optimal glass sample reaches 86% of that of Bi4Ge3O12 (BGO), surpassing that of most broadband-emitting glass scintillators. In practical application, it delivers a high imaging resolution of 20 lp/mm. Thirdly, by utilizing energy transfer from traps to Mn2+, optimal glass sample exhibits zero-thermal-quenching luminescence (XEL intensity at 423 K is 101% of that at room temperature). Particularly, its XEL intensity at 543 K retains 61% of that at room temperature, far exceeding those of commercial scintillators CsI:Tl and BGO. Our work indicates that Mn2+-doped oxyfluoride glass has broad prospects as broadband-emitting scintillators for high-temperature X-ray imaging. These strategies open new avenues for the development of thermal-stable glass scintillators.
