Abstract
The results of 31P NMR Knight shift (KS) and spin-lattice relaxation time (T1) as well as magnetic susceptibility (ξ) measurements in the temperature interval 4.2-300K are reported for the compounds RENi2P2(RE = Ce, EuandYb) in order to understand the nature of the 41 magnetism in these compounds. The KS results conclusively establish that all these compounds exhibit non-magnetic ground states. There is a low-temperature upturn in ξ for CeNi2P2 and YbNi2P2 presumably due to magnetic impurities. The estimated spin fluctuation temperatures (Tsf) for EuNi2P2 above 50K agree qualitatively with those obtained earlier from Mössbauer and ξ data employing ionic interconfigurational fluctuation model, but seem to disagree at low temperatures. Implications of this result are discussed.
