铜氧化物中的长程反铁磁序与这些化合物中的高温超导性之间的关系，是一个近四十年仍未解决的科学难题。由于最近发现的镍酸盐超导体是铜氧化物的晶体学对应物，许多性质和描述这些化合物的困难对两个家族来说是共同的。最近，Fowlie等人（2022 Nature Physics 18 1043）旨在通过使用μ子自旋旋转（muSR）技术检测R_{1-x}Sr_{x}NiO_{2}（R = Nd, Pr, La, x ~ 0.2）薄膜中的反铁磁序。该研究小组报告了在所有研究的镍酸盐中存在短程反铁磁序。在这里，我们旨在通过分析同一研究小组报告的温度依赖电阻率ρ(T)，揭示同一镍酸盐薄膜中这种相互作用的存在。对先进Bloch-Grüneisen模型的全局ρ(T)数据拟合表明，每种R1-xSrxNiO2化合物都可以用唯一的幂律指数p（其中p=2表示电子-电子散射，p=3表示电子-磁振子散射，p=5表示电子-声子散射）和全局特征温度T_ω（在p=5时具有德拜温度的含义）来表征。我们发现Nd基和Pr基化合物的p=2.0，La基化合物的p=1.3。后一个值在已建立的理论模型内没有任何解释。我们还分析了Lee等人（2022 arXiv2203.02580）报告的Nd_{1-x}Sr_{x}NiO_{2}（0.125 < x < 0.325）的ρ(T)数据。由于我们的分析表明镍酸盐中的p值与p=3显著不同，我们呼吁开发一种新的理论模型来描述具有短程反铁磁序的材料中的ρ(T)。
英文摘要：
The relationship between the long-range antiferromagnetic order in cuprates and the high-temperature superconductivity in these compounds represents unresolved, nearly four-decades long scientific problem. Because recently discovered nickelate superconductors are crystallographical counterparts of cuprates, many properties and difficulties into describing these compounds are common to both families. Recently, Fowlie et al (2022 Nature Physics 18 1043) aimed to detect the antiferromagnetic order in $R_{1-x}Sr_{x}NiO_{2}$ (R = Nd, Pr, La, x ~ 0.2) films by using the muon spin rotation (muSR) technique. This research group reported on the existence of short-range antiferromagnetic order in all studied nickelates. Here, we aimed to reveal the existence of this interaction in the same nickelate films by analyzing the temperature dependent resistivity, $ρ(T)$, reported by the same research group. Global $ρ(T)$ data fits to the advanced Bloch-Grüneisen model showed that each of R1-xSrxNiO2 compounds can be characterized by a unique power-law exponent, p (where p=2 for the electron-electron scattering, p=3 for the electron-magnon scattering, and p=5 for the electron-phonon scattering), and global characteristic temperature, $T_ω$ (which has the meaning of the Debye temperature at p=5). We found that p=2.0 in Nd- and Pr-based compounds, and p=1.3 for La-based compound. The latter value does not have any interpretation within established theoretical models. We also analyzed $ρ(T)$ data for $Nd_{1-x}Sr_{x}NiO_{2}$ (0.125 < x < 0.325) reported by Lee et al (2022 arXiv2203.02580). Because our analysis showed that p-values in nickelates are remarkably different from p=3, we call for the developent of a new theoretical model to describe $ρ(T)$ in materials exhibiting a short-range antiferromagnetic order.
