Description
The crystalline-electric-field (CEF) parameters for the Pr3+ ion in nonmagnetic PrNi2Al5 has been estimated using the 27Al nuclear magnetic resonance (NMR) Knight shift, K, measured in a grain-aligned sample in the temperature range 3.5-310 K. The behaviour of the shift is well explained by van Vleck paramagnetism. The overall crystal-field splitting (Δ), obtained from the temperature dependence of K, is at least 100 K more than the value reported from magnetic susceptibility measurements. Moreover, the first two low lying excited states are 44 and 96 K above the ground level
