Magnetic Susceptibilities of Rare-Earth–Indium Compounds: RIn3

Abstract

The magnetic properties and the lattice parameters for 13 compounds of the composition RIn3 (Cu3Au structure) are reported. The magnetic measurements have been performed between 4.2° and 500°K with magnetic fields up to 30 kOe. With the exception of compounds with R=La, Sm, Y, and Yb Curie–Weiss behavior is observed in the high-temperature region. At low temperatures the magnetic behavior for compounds in which R=Ce, Nd, Sm, Gd, Tb, Dy, Ho, and Er is ascribed to antiferromagnetic ordering. In the case of PrIn3 magnetic ordering is prevented by crystalline fields. The splitting of the J = 4 state of Pr3+ by cubic crystalline fields has been calculated for various combinations of fourth- and sixth-order potentials. Possible energy diagrams are presented.

Low-temperature specific heat study of antiferromagnetic transition in ternary rare-earth metal silicide R5Ir4Si10 (R = Tb, Dy, Ho, Er)

“…6, in the ternary rare-earth metal silicides R 5 Ir 4 Si 10 (R=Tb, Dy, Ho, Er) the antiferromagnetic transition temperature T N increases when the de Gennes factor of the rare-earth metal increases like as the binary compound Rln 3 (R =Gd, Tb, Dy, Ho, Er) [6] and the ternary compound RCu 2 Ge 2 (R= Gd, Tb, Dy, Ho, Er) [7]. This result means that we need not take the crystalline electric field effects into consideration in the R 5 Ir 4 Si 10 compounds.…”

Magnetic and transport properties of ternary indides of type R2CoIn8 (R=Ce, Pr, and Dy)

“…1. Such a behavior is usually attributed to the crystalline electric field (CEF) effects [5], which remove the degeneracy of the ground state of the rare earth ion. The splitting of the (2J+1)-fold degenerate ground state of the Pr 3+ ion results in a singlet CEF ground state.…”

Low temperature properties of some RIn3 compounds

“…The first comprehensive study of the magnetic susceptibilities of the RIn 3 compounds was published by Buschow, et al [9] in 1969. Nearly all of the compounds (R = Ce, Nd, Sm, Gd, --- [9] There are a few things to note in Table 1 by approximately 1 K.…”

“…Although this difference is only 0.33%, it still is considerably higher than what is considered to be a typical experimental error for x-ray analysis, which is usually on the order of 0.005%.
