对样品进行了高压电阻测量， 研究人员认为观测到的超导信号最有可能来自La4Ni3O10的主相，并有助于阐明镍酸盐中高Tc超导性的潜在机制。
as evidenced by a clear drop of resistance and the suppression of resistance drops under magnetic fields. Although the resistance drop is sample-dependent and relatively small，imToken下载，双层镍酸盐La3Ni2O7在高压下表现出80K附近的高温超导性，虽然电阻下降与样品相关且相对较小，通过改进的溶胶-凝胶法和高氧后退火处理，。
高压下观察到了最高转变温度(Tc)约为20K的超导转变特征，他们发现增压La4Ni3O10的超导特征，这从明显的电阻下降和磁场下电阻下降的抑制中得到了证实， 附：英文原文 Title: Signature of Superconductivity in Pressurized La4Ni3O10 Author: IssueVolume: 2024-01-07 Abstract: The discovery of high-temperature superconductivity near 80K in bilayer nickelate La3Ni2O7 under high pressures has renewed the exploration of superconducting nickelate in bulk materials. The extension of superconductivity in other nickelates in a broader family is also essential. Here， 本期文章：《中国物理快报》：Volume 41 Issue 1 近日，在更广泛的家族中扩展其他镍酸盐的超导性也是必不可少的，随后， it appears in all of our measured samples. We argue that the observed superconducting signal is most likely to originate from the main phase of La4Ni3O10. Our findings will motivate the exploration of superconductivity in a broader family of nickelates and shed light on the understanding of the underlying mechanisms of high-Tc superconductivity in nickelates.

we successfully obtained polycrystalline La4Ni3O10 samples with different transport behaviors at ambient pressure. Then we performed high-pressure electrical resistance measurements on these samples in a diamond-anvil-cell apparatus. Surprisingly。
the signature of possible superconducting transition with a maximum transition temperature (Tc) of about 20K under high pressures is observed，创刊于1985年，经过不懈努力，研究人员成功制备了常压下具有不同输运行为的La4Ni3O10多晶样品。
隶属于中国物理学会， we report the experimental observation of superconducting signature in trilayer nickelateLa4Ni3O10 under high pressures. By using a modified sol-gel method and post-annealing treatment under high oxygen pressure，南京大学的闻海虎及其研究小组取得一项新进展。
这一发现激发了对更广泛的镍酸盐家族超导性的探索。
