Phonon Symphony of Stacked of Multilayer and Weakly Bond Lowering Lattice Thermal Conductivity. Adv Mater (2022)

摘要

降低晶格振动获得固有的低热导率材料在电光器件、能量转换器和热绝缘体领域极具潜力，而晶格振动的降低需要探索新的化合物，并深入了解材料的化学结构、键合和晶格动力学。其中，一种新的硫族化合物Ga₆Cr₅Se₁₆具有固有的低晶格热导率κ_lat，该材料为单斜结构 (C2/m)，沿c轴依次堆积不同原子层，每一层都排列着各种各样的化学键，如共价键Ga-Se和Cr³⁺ -Se，以及较弱的Cr²⁺ -Se键，通过软声学声子和低能光学声子的强耦合形成声子和弦。因此， Ga₆Cr₅Se₁₆在323 K时实现了固有低热导κ_lat=0.79 W m⁻¹ K⁻¹，这几乎是Cr₃Se₄ (2.95 W m⁻¹ K⁻¹)、Cr₂Se₃ (1.56 W m⁻¹ K⁻¹)、Ga₂Se₃ (1.36 W m⁻¹ K⁻¹)在323 K时的1/4或1/2。这篇工作将为复杂层状硫族化合物中声子的传播提供全面的理解，也为未来低热导κ_lat固体的设计提供新的思路。

Variation between Antiferromagnetism and Ferrimagnetism in NiPS3 by Electron Doping. Advanced Functional Materials (2022)

摘要

电子控制材料磁性在自旋电子领域具有广阔的应用前景，但由于反铁磁(AFM)材料的净磁化强度为零，载流子掺杂效应的研究仍具有挑战性。在这项工作中，作者发现2D AFM绝缘体NiPS₃磁序随电子掺杂变化，其中电子掺杂是在NiPS₃的vdWs隙中插入各种有机阳离子，这种掺杂不引入缺陷和杂质相。掺杂水平为每晶胞0.2 ~ 0.5电子时，材料发生AFM -亚铁磁(FIM)转变，掺杂水平为每晶胞≥0.6电子时发生FIM- AFM转变。作者认为，转变的发生是在以Stoner交换为主导的链间FM序和以超交换为主的AFM序之间存在竞争所致。该研究为通过2D磁性材料的电子结构与磁性之间的相关性为实现磁电效应提供了一种可行的方法。

摘要

提高金属的原子利用率和阐明M-M’相互作用对组装高性能超轻型电磁波吸波材料都具有重要意义。本文采用高温爆炸，通过热解高能金属有机骨架，成功地组装出带有Co-Fe修饰的多层次的多孔碳海绵。这种复合材料的反射损失值(RL)为−57.7 dB，在12.08 GHz时，特定RL值为−192 dB mg⁻¹ mm⁻¹，层厚为2.0 mm(加载量为15%)。离轴电子全息图表征了高度分布的大量极化纳米畴可变电容，具有沿纳米孔边缘的偶极子和界面极化。更重要的是，X射线吸收光谱分析验证了金属团簇与碳基体之间的相互作用以及电子耦合作用极大提高了电磁波吸收率。

Pressured-induced superconducting phase with large upper critical field and concomitant enhancement of antiferromagnetic transition in EuTe₂. Nat Commun (2022)

摘要

该篇工作在EuTe₂中发现了不寻常的压力诱导超导态，与Eu²⁺的反铁磁有序态共存，并显示了一个较大的上临界场，可与EuTe₂的泡利顺磁极限相当。当压力超过P_c≈ 6 GPa时，超导转变出现在T_c ≈ 3 – 5 K ，并同时伴随有反铁磁转变温度 T_N(P) 较快上升，斜率急剧增大，从dT_N/dP = 0.85(14) K/GPa (P ≤ P_c)上升到3.7(2) K/Gpa (P ≥ P_c) 。此外，在μ₀H ≥ 2 T的中等磁场下，超导转变在Eu²⁺亚晶格自旋转向存在铁磁净分量的情况下，仍然存在。总结而言，该篇工作证实了加压EuTe₂是一种罕见的磁性超导体，具有磁性和超导性之间的密切相互作用。

Physical realization of topological Roman surface by spin-induced ferroelectric polarization in cubic lattice. Nat Commun (2022)

摘要

拓扑，作为一个重要的数学分支，是描述拓扑态和相变的理想理论工具。许多拓扑概念在由拓扑不变量确定的实空间或倒易空间中找到了它们的物理实体，这些不变量通常定义在可定向曲面上，如环面和球面。更有趣的不可定向曲面的可能的物理实现研究极具挑战。在此，该篇工作证明了在立方钙钛矿氧化物 AMn₃Cr₄O₁₂ (A = La和Tb)中，自旋诱导的铁电极化的集合位于拓扑罗马曲面上——一个不可定向的二维流形，通过将Möbius带缝到圆盘边缘而形成。诱导极化可能沿着不可定向的Möbius带或可定向盘，这取决于由外部磁场诱导的自旋演化。实验结果表明，极化周期可以与旋转磁场周期相同，也可以是旋转磁场周期的两倍，这与圆盘和Möbius带的定向性一致。这种路径相关的拓扑磁电效应提供了一种检测表面整体几何形状的方法，加深了我们在数学和物理上对拓扑的理解。

Amelioration of systemic antitumor immune responses in cocktail therapy by immunomodulatory nanozymes. Science Advances

摘要

模拟天然酶样活性的纳米酶逐渐出现在癌症治疗中。为了克服单模纳米酶的瓶颈，包括“脱靶”毒性和对转移性癌症无效，我们设计了基于磁性纳米颗粒的多功能可视化免疫调节纳米酶。这些纳米酶除了通过固有免疫原性部分启动免疫反应外，作为一种对肿瘤微环境的温度和pH双重反应的智能给药系统，通过释放免疫激动剂来增强全身免疫反应，最终实现改善肿瘤免疫微环境的多种策略，包括：激活树突状细胞，提高CD⁸⁺ T细胞的功能，减少骨髓源性抑制细胞的数量，从而抑制原发性和转移性癌症。机制上，这些纳米酶调控活性氧相关的Akt信号通路，进而激活细胞凋亡相关的信号通路，为进一步理解多功能纳米酶的协同作用机制提供了依据。

Fe_3–xInSn_xO₆ (x = 0, 0.25, or 0.5): A Family of Corundum Derivatives with Sn-Induced Polarization and Above Room Temperature Antiferromagnetic Ordering. Chemistry of Materials (2022)

摘要

三种新的双刚玉衍生化合物 Fe_3–xInSn_xO₆(x = 0. 0.25, or 0.5) ，在6 GPa, 1400-1450 ℃下合成。所有化合物在室温以上都为反铁磁序AFM，转变温度分别为 T_N = 608, 532, 432 K 对于 x = 0, 0.25, 0.5 。x = 0相结晶为中心对称的R3̅c ，而封闭壳层d¹⁰ Sn⁴⁺的加入使x = 0.25和0.5结晶为非中心对称的R3c。微探针测量表明，当x = 0.25和0.5时，Sn⁴⁺的取代不会被空位所抵消，这意味着Fe²⁺的存在，并被X射线吸收近边光谱和单晶X射线结构细化所证实。中子粉末衍射实验表明，x = 0.5化合物是倾斜的A型AFM，与Fe₂O₃和InFeO₃一样，由铁磁层的反铁磁堆叠构成，具有一个磁相变，其弱铁磁相互作用持续到非常高的温度。温度依赖的二次谐波产生(SHG)测量结果显示，x = 0.25和0.5的化合物，SHG响应在磁相变中具有类似铁电的回滞极大值，暗示了磁序和极化有序的耦合。这些新化合物为寻找可调高温磁电材料提供了更多电子、磁性和结构特性的信息。

Magnetization measurements were carried out in a magnetometer with a superconducting quantum interference device (SQUID). Field-cooled (FC) and zero-field-cooled (ZFC) magnetic measurements were taken in the temperature range of 5−400 K with an applied magnetic field of 1 T and in the range of 400−800 K at 0.5 T. Isothermal magnetization curves were obtained at 5, 100, 150, and 300 K under an applied magnetic field ranging from 6 to −6 T.

Pressure-Induced Superconductivity up to 9 K in the Quasi-One-Dimensional KMn₆Bi₅. Physical Review Letters (2022)

摘要

锰基超导体因较强的磁对破缺效应而十分罕见。本文KMn₆Bi₅压力诱导超导的发现，使它成为第一个三元锰基超导体。在环境压力下，准一维KMn₆Bi₅为AFM，转变温度T_N≈75 K。在高达14.2 GP静水压力下的电阻和交流磁化率的测量，发现当临界压力达到P_c≈13 GPa时，其AFM转变被完全抑制，超导转变出现，最高超导转变温度T_C=9.3 K@14 GPa。KMn₆Bi₅的温压相图超导和磁失稳的相邻，以及超过泡利顺磁极限的巨大上临界场 μ₀H_c2(0) ，都暗示了一种非常规的磁介导配对机制。与二元MnP相比，三元AMn₆Bi₅ (A=碱金属)的晶体结构和化学组成的灵活性为发现更多锰基超导体开辟了新道路。

Thickness-dependent and strain-tunable magnetism in two-dimensional van der Waals VSe₂. Nano Research (2022)

摘要

二维(2D)范德华(vdW)的低维磁性材料相比于其体材料，往往表现出意想不到的特性。特别是二维结构柔性、铁磁性的增强以及强大的垂直磁各向异性对构建新型自旋电子器件非常有吸引力。vdW二硒化钒VSe₂体材料是顺磁性，而单层却呈现出铁磁性，且居里温度(T_c)高于室温。为了探索其应用潜力，对VSe₂进行了厚度依赖的磁性和应变调制研究。本文采用化学气相沉积(CVD)法制备了不同层厚的VSe₂纳米薄片。在室温下发现几层厚的VSe₂纳米薄片具有磁畴结构。磁力显微镜(MFM)相位图像显示了明显的厚度依赖性磁性和MFM相位对比是可追踪的层厚低于6 nm的纳米薄片。在室温下，施加应变可以有效地调制二维VSe₂的磁矩和矫顽力场。这些结果有助于理解高温二维磁体的铁磁性，也有助于构建新型的应变电子器件或柔性自旋电子器件。

Mosaic growth induced magnetic anisotropy in double perovskite PrBaCo₂O_5+δ thin films. Acta Materialia (2022)

摘要

控制晶体结构是调控层状钙钛矿氧化物物理性质的关键步骤之一。本文生长了马赛克拼接式的双钙钛矿PrBaCo₂O_5+δ (PBCO)薄膜，并进行生长动力学及磁各向异性(MA)研究。高分辨率X射线衍射和扫描透射电子显微镜研究表明，PBCO薄膜的晶体结构具有高度定向性，有三种变体，即<100>(013)晶粒沿a或b轴向[00l]方向倾斜±18°，<110> (001)畴沿c轴旋转45°，以及常见的立方对立方<100> (001)外延。在马赛克拼接的纳米结构薄膜中观察到MA向各向同性的转变和异常的各向异性磁阻。这些证据不仅突出了钙钛矿体系中纳米结构与物理性质之间的相关性，而且提供了控制定向纳米结构来操纵MA的新途径，为通过纳米结构设计创造未来的纳米电子学和自旋电子器件铺平了道路。

PPMS Resistivity & Ratator + MPMS

The magnetic properties were measured by Superconductor Quantum Interference Device (SQUID, Quantum Design, MPMS3). To investigate the MA, magnetic hysteresis loops were conducted at 50 K along in-plane (IP) and out-of-plane (OP) directions in succession. The electric transport properties were determined using the standard four-point probes technique within the Physical Property Measurement System (PPMS, Quantum Design), to check the in-plane angle dependence of magnetoresistance. The controllable angle between the direction of current and magnetic field was achieved by rotating the sample holder.
