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.
