This paper reviews recent breakthroughs in spintronics, which have achieved ultrafast switching speeds and ultra-low energy consumption in magnetic tunnel junctions. By integrating advanced materials, such as topological insulators, two-dimensional ferromagnets, and heavy metals, we found the room-temperature stabilization of skyrmions with storage densities exceeding 1Tb/in², enabling high-density nonvolatile memory. Furthermore, a hybrid complementary metal-oxide semiconductor-spintronic architecture is discussed, which reduces power consumption by 30 % in neuromorphic computing applications while maintaining compatibility with existing semiconductor technologies. Key innovations, such as optimized cobalt-iron-boron/magnesium oxide interfaces for tunneling magnetoresistance ratios exceeding 300 %, efficient spin-charge conversion in heavy metals, and voltage-controlled skyrmion devices for sub-0.1 pJ/bit operation, are also discussed. These advancements address scalability, thermal stability, and fabrication challenges, positioning spintronics as a cornerstone for next-generation memory, logic devices, and quantum computing. We also found that spintronic neuromorphic systems can achieve 20 <em>TOP/s/w</em>, outperforming traditional artificial intelligence accelerators. At the same time, spin qubits with 99.9 % fidelity offer a scalable pathway to quantum computing, underscoring spintronics' potential to revolutionize artificial intelligence, the Internet of Things, and quantum technologies, providing energy-efficient, high-performance solutions for the post-Moore era. Future efforts will focus on three-dimensional magnetic tunnel junction stacking with densities exceeding 1 Tb/mm³, and defect-tolerant materials for large-scale commercialization.</div></div>","PeriodicalId":17219,"journal":{"name":"Journal of Science: Advanced Materials and Devices","volume":"11 1","pages":"Article 101087"},"PeriodicalIF":6.8,"publicationDate":"2025-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145837499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This metastructure was fabricated via Fused Deposition Modeling (FDM) using a polyether ether ketone/flaky carbonyl iron particles (PEEK/FCIPs) composite. Simulation and experiment have demonstrated that the metastructure synergistically integrates multiple dissipation mechanisms, including quarter-wavelength resonance, multicavity resonance, and edge diffraction.

Experimental results agree well with the simulations, and also reveal excellent angular stability that maintains effective absorption up to 45° for both transverse electric (TE) and transverse magnetic (TM) polarizations.

Poly-ether-ketone-ketone (PEKK), a high-performance thermoplastic, offers considerable promise for aerospace applications. However, its mechanical behavior in material extrusion (MEX) remains constrained by pronounced anisotropy and weak interlayer bonding. Addressing these limitations requires understanding how printing architecture and post-processing jointly influence mechanical response. Therefore, the objective of this study is to evaluate the effectiveness of an optimized annealing protocol, established in our previous work (210 °C for 30 min), in reducing anisotropic behavior and enhancing mechanical performance across different raster orientations and architected structures. Tensile and flexural coupons were fabricated at raster angles of 0°, ±45°, and 90° using three infill patterns (line, concentric, and mixed) and tested before and after annealing. Additionally, compressive coupons of Schwarz G and Schwarz P lattices with 40 % relative density were examined to represent structural architected geometries, tested both parallel and perpendicular to the print-layer direction. Results show that reinforcement by annealing is pattern-dependent. At the maximum reinforcement, concentric infill yielded the greatest tensile strength improvement (29.5 %), whereas the 90° raster exhibited the largest flexural strength gain (17.6 %). For structural lattices, compressive strength increased by 37.5 % in Schwarz G, while a reduction of 18.6 % was observed in Schwarz P. While annealing enhanced stiffness, strength, and thermal stability, it also introduced dimensional changes and occasional void-related defects. Overall, this study demonstrates the interplay between anisotropic printing architecture and post-processing, providing pathways to tailor PEKK components for aerospace and structural applications requiring either superior strength (annealed) or enhanced toughness (as-printed).</div></div>","PeriodicalId":17219,"journal":{"name":"Journal of Science: Advanced Materials and Devices","volume":"11 1","pages":"Article 101077"},"PeriodicalIF":6.8,"publicationDate":"2025-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145798204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
