DESCRIPTION:Speakers: Andre Strydom (University of Johannesburg)\nThe nove
 l ternary intermetallic compound Ce6Pd12In5 forms in a well-defined atomic
  stoichiometry with a hexagonal crystal structure (space group P63/mcm) an
 d a unique atom in each of the crystallographic sites available in this sp
 ace group. The bonding lengths are comparatively short and suggest strong 
 interaction especially between Ce and Pd atoms. \nIn this work we report o
 n our findings of the first studies into the physical properties of Ce6Pd1
 2In5. A key finding is the occurrence of long-range ferromagnetic-like ord
 er below TC =1.6 K\, where the specific turns into a lambda-like anomaly p
 eaking at CP = 8 J/(mol Ce K). The electrical resistivity hints at a low-l
 ying Kondo scale in this compound. The magnetic susceptibility shows well-
 defined Curie-Weiss behaviour over an extended temperature range with an e
 ffective magnetic moment value that is indicative of conduction-electron h
 ybridization effects on the Ce localized moment. The 4f–electron derived
  magnetic contributions to the entropy and to the electrical resistivity i
 n Ce6Pd12In5 are assessed by means of the nonmagnetic counterpart La6Pd12I
 n5.\n\nhttps://events.saip.org.za/event/7/contributions/5022/
