These states induce opposite signs of the Hall effect proportional to magnetization, which is widely used for their electrical read-out. By contrast, conventional antiferromagnets with a collinear antiparallel spin configuration cannot host such functions, because of <span>({mathcal{T}}{mathrm{t}})</span> symmetry (time-reversal <span>({mathcal{T}})</span> followed by translation t symmetry) and lack of macroscopic magnetization. Here we report the experimental observation of a spontaneous Hall effect in the collinear antiferromagnet FeS at room temperature. In this compound, the ‚Üë‚Üì and ‚Üì‚Üë spin states induce opposite signs of the spontaneous Hall effect. Our analysis suggests that this does not reflect magnetization, but rather originates from a fictitious magnetic field associated with the <span>({mathcal{T}}{mathrm{t}})</span>-symmetry-broken antiferromagnetic order. The present results pave the way for electrical reading and writing of the ‚Üë‚Üì and ‚Üì‚Üë spin states in conductive systems at room temperature, and suggest that <span>({mathcal{T}}{mathrm{t}})</span>-symmetry-broken collinear antiferromagnets can serve as an information medium with vanishingly small magnetization.</p>","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"4 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142815546","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}

Therapeutic strategies targeting reactive oxygen species levels in pneumonia have limited success due to the intricate nature of lung tissues and lung inflammatory responses. Here we describe an inhalable, non-invasive therapeutic platform composed of engineered cerium-based tannic acid nanozymes bound to a self-assembling peptide. In vitro and in vivo studies show that the nanozyme is internalized mostly by activated macrophages and epithelial cells in the inflamed sites. In the oxidative environments of a mouse model of viral pneumonia, nanozyme aggregates into catalytically active structures that reduce reactive oxygen species levels and inflammatory cytokine production and promote macrophage polarization to the prohealing (M2) phenotype. Moreover, the nanozyme attenuates bacterial inflammation and reduces tissue damage in a mouse viral pneumonia model with secondary bacterial infection. Overall, this nanozyme platform is a promising strategy for treating pneumonia and its associated conditions.</p>","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"77 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142713248","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}
