The present paper reports the nuclear
hyperfine properties of KNd3F10 with the help of crystal
field theory after finding the crystal field parameters
which are essential for the aforesaid properties . The
observed g-values of the sample were well explained with
this theory with the comparison with some other
samples. The nuclear hyperfine levels of 143Nd has been
determined . The hyperfine specific heat for KNd3F10 has
shown an inverse T2
(where T represents temperature)
rule in millikelvin temperature range.
Keywords : Crystal Field Effect, G-Values, Hyperfine Interaction, Hyperfine Specific Heat.
