27Al NMR studies in grain-aligned PrNi2Al5

27Al Knight shift (K) in grain aligned PrNi2Al5 has been measured, in the temperature range 3.5-320K, for two crystallographic non-equivalent Al sites. K becomes independent of temperature below in each case. chif(T) for a Pr3+ ion in the orthorhombic crystal-field has been calculated to estimate th...

Zusammenfassung:	27Al Knight shift (K) in grain aligned PrNi2Al5 has been measured, in the temperature range 3.5-320K, for two crystallographic non-equivalent Al sites. K becomes independent of temperature below in each case. chif(T) for a Pr3+ ion in the orthorhombic crystal-field has been calculated to estimate the crystalline-electric-field (CEF) coefficients using K. The over-all crystal-field splitting (Delta) is and CEF energy from the ground state to the first excited state is .
