{"title":"Pressure-enhanced spin-density-wave transition in double-layer nickelate La₃Ni₂O_7-δ.","authors":"Dan Zhao, Yanbing Zhou, Mengwu Huo, Yu Wang, Linpeng Nie, Ye Yang, Jianjun Ying, Meng Wang, Tao Wu, Xianhui Chen","doi":"10.1016/j.scib.2025.02.019","DOIUrl":"https://doi.org/10.1016/j.scib.2025.02.019","url":null,"abstract":"<p><p>Recently, a signature of high-temperature superconductivity above the liquid nitrogen temperature (77 K) was reported for La₃Ni₂O_7-δ under pressure. This finding immediately stimulated intense interest in the possible mechanism of high-T_c superconductivity in double-layer nickelates. Notably, the pressure-dependent phase diagram inferred from transport measurements indicates that the superconductivity under high pressure emerges from the suppression of density-wave-like order at ambient pressure, which is similar to high-temperature superconductors. Therefore, clarifying the exact nature of the density-wave-like transition is important for determining the superconducting mechanism in double-layer nickelates. Here, nuclear magnetic resonance (NMR) spectroscopy of ¹³⁹La nuclei was performed to study the density-wave-like transition in a single crystal of La₃Ni₂O_7-δ. At high temperatures, two sets of sharp ¹³⁹La NMR peaks are clearly distinguishable from a broad background signals, which are ascribed to La(1) sites from two bilayer Ruddlesden-Popper phases with different oxygen vacancy δ. As the temperature decreases, the temperature-dependent ¹³⁹La NMR spectra and nuclear spin-lattice relaxation rate (1/T₁) for both La(1) sites provide evidence of spin-density-wave (SDW) ordering below the transition temperature (T_SDW), which is approximately 150 K. The anisotropic splitting in the NMR spectra suggests the formation of a possible double spin stripe with magnetic moments aligned along the c-axis. Furthermore, we studied the pressure-dependent SDW transition up to ∼ 2.7 GPa. Surprisingly, the T_SDW inferred from NMR measurements of both La(1) sites increases with increasing pressure, which is opposite to the results from previous transport measurements under pressure and suggests an intriguing phase diagram between superconductivity and SDW. In contrast, the present ¹³⁹La NMR is insensitive to the possible charge-density-wave (CDW) order in the Ni-O planes. All these results will be helpful for building a connection between superconductivity and magnetic interactions in double-layer nickelates.</p>","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":18.8,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the further improvement of HER activity is limited by the unfavorable interaction of hydroxyl generated by the dissociation of water with active sites. Herein, we propose a strategy of alkaline earth metal cations-driven electron delocalization to elaborately tailor the binding of hydroxyl with the active sites. Taking FeNiMg-layered double hydroxides (FeNiMg-LDH) as a prototypical example, the combined operando spectroscopy analysis and theoretical calculations show that the introduction of Mg cations in solid- solution phase can create a local electronic field and delocalize the electron between Fe and adsorbed hydroxyl, resulting in an optimization of hydroxyl binding strength. Accordingly, FeNiMg-LDH lowers the overpotentials to deliver 10 mA cm^-2 in alkaline electrolyte by 39 and 64 mV, compared to FeNi-LDH and Ni-LDH catalysts, respectively. This work sheds new light on the rational design of advanced HER electrocatalyst for alkaline water electrolysis.</p>","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":18.8,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143536379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
