Abstract

Electric quadrupole effects in a Pr-based clathrate compound Pr 3 Pd 20 Si 6 have been investigated by ultrasonic measurements. Elastic constants of ( C 11 - C 12 ) /2 and C 44 in Pr 3 Pd 20 Si 6 show curie-type softenings with decreasing temperature below 20 K, which are described in terms of quadrupole effects of 4f-electron for the ground state either Γ 3 doublet or Γ 5 triplet. H – T phase diagram of Pr 3 Pd 20 Si 6 under the magnetic fields along [110] is obtained from elastic anomalies in ( C 11 - C 12 ) /2 mode.
