用~(31)P-NMR方法研究了铁磁量子临界系统YbNi 4P 2.这是一个新发现的重费米子系统,在很低的TC = 170 mK处出现FM跃迁。目前报道的结果是我们以前的工作发表在参考文献11.31P NMR结果表明,在存在强FM相关的Korringa定律的有效性。31 P NMR谱显示各向异性的性质。从我们的NMR谱中得到的局部磁化强度在选定的温度下作为场的函数。得到的自旋晶格弛豫率31(1/T1 T)在T = 1.8 K的宽场范围内遵循弱幂律,T =-0.75。这种不寻常的幂律行为的可能情况进行了讨论。此外,在重整化朗道费米液体理论的框架内,31(1/T1 T)与在1.8-10 K温度范围内观察到的(C/T)2 <$T− 0.8幂律很好地标度。
The ferromagnetic (FM) quantum critical system YbNi4P2has been investigated by means of31P‐NMR. This is a newly discovered heavy fermion system which shows a FM transition at a very lowTC= 170 mK. The present reported result is the extension of our previous work published in Ref. 11.31P NMR results suggest the validity of the Korringa law in the presence of strong FM correlations.31P NMR spectra have shown the anisotropic nature. The local magnetization derived from our NMR spectra is presented as a function of field at selected temperatures. The obtained spin‐lattice relaxation rate31(1/T1T) follows a weak power‐law asT−0.75in a wide field range down toT= 1.8 K. Possible scenarios for this unusual power‐law behavior are discussed. Additionally,31(1/T1T) is nicely scaled with the observed (C/T)2∼T−0.8power law in the temperature range 1.8–10 K within the framework of renormalized Landau Fermi Liquid theory.
