Although the switching of antiferromagnetic (AFM) order by current-induced spin–orbit torque (SOT) has already been realized, field-free SOT-induced bidirectional switching of AFM order in perpendicular geometry has been elusive. Here we experimentally demonstrate field-free perpendicular switching of the magnetic octupole moct in chiral AFM Mn3Sn by combining in-plane and out-of-plane SOTs generated by two-dimensional van der Vaals WTe2. The out-of-plane SOT breaks the in-plane inversion symmetry and leads to deterministic bidirectional switching of moct in polycrystalline Mn3Sn even without a fixed perpendicular moct easy axis. The switching ratio reaches up to 80% compared to 20–30% in polycrystalline Mn3Sn and the critical current density is reduced by an order of magnitude to around 1 MA cm−2. Our work promotes the development of chiral AFM devices toward practical application.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"25 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143884793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of their brittleness, semiconductors are usually processed by the complicated techniques of sputtering or deposition2,3,4, instead of the effective and versatile metalworking methods like rolling, extrusion and pressing used with metals5. Here we show that brittle semiconductors can be plastically manufactured with an extensibility as large as ~3,000% using warm metalworking, that is, plastic manufacturing at slightly elevated temperatures (empirically below 500 K). Many bulk brittle semiconductors, such as Cu2Se, Ag2Se and Bi90Sb10, can be processed like metals below 400–500 K into free-standing, large and high-quality films with a thickness from the macro-scale to the micrometre scale. A model based on temperature-dependent collective atomic displacement and thermal vibration is proposed to explain the superior plasticity. The warm-metalworked films can retain the excellent and tunable physical properties of the bulk versions, such as a high carrier mobility up to ~5,000 cm2 V−1 s−1 and tunable electrical conductivities over six orders of magnitude by adjusting the chemical composition. A case study in film thermoelectric devices demonstrates ultra-high normalized output power densities of 43–54 μW cm−2 K−2. This work suggests that brittle semiconductors can be manufactured by warm metalworking for applications in various electronics.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"36 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143880490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we propose a molecular-force-driven anisotropy strategy to modulate the molecular orientation of conjugated polymers. This strategy relies on the intermolecular interactions, gauged by the Hansen solubility parameters framework, to provide solvent selection criteria for conjugated polymers that render films with a preferential orientation. We showcase molecular-force-driven anisotropy to overcome the inverse coupling between the electrical conductivity and Seebeck coefficient in solution-processed organic thermoelectrics, a major challenge in the field. Our kinetic Monte Carlo simulations suggest that edge-on orientations break the trade-off by increasing the in-plane delocalization length. The molecular-force-driven anisotropy approach yields a power factor of 115 μW m−1 K−2 and a figure of merit of 0.17 at room temperature for the doped n-type 2DPP-2CNTVT:N-DMBI system. This power factor is 20 times larger than that of conventional doping approaches.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"72 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143880500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we present an approach that uses a generative machine learning model based on diffusion processes that are trained on 45,229 known structures. The model factors measured the diffraction pattern as well as the relevant statistical priors on the unit cell of atomic cluster structures. Conditioned only on the chemical formula and the information-scarce finite-sized broadened powder diffraction pattern, we find that our model, PXRDnet, can successfully solve the simulated nanocrystals as small as 10 Å across 200 materials of varying symmetries and complexities, including structures from all seven crystal systems. We show that our model can successfully and verifiably determine structural candidates four out of five times, with an average error among these candidates being only 7% (as measured by the post-Rietveld refinement R-factor). Furthermore, PXRDnet is capable of solving structures from noisy diffraction patterns gathered in real-world experiments. We suggest that data-driven approaches, bootstrapped from theoretical simulation, will ultimately provide a path towards determining the structure of previously unsolved nanomaterials.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"1 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143880527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
