Magnetic properties of PrIn3 and TmIn3 in magnetic fields up to 40 T

Effect of Strains on Magnetic Ordering in TmIn3

“…The low temperature magnetic properties therefore should be strongly influenced by the crystal field. Since no lattice distortion was found, we made a comparison of the neutron results with calculations based only on crystal-field models proposed in [2] and [3]. In the ordered state a rare earth system can be described by a Hamiltonian consisting of a crystal-field and exchange term: H = H cf + H ex .…”

“…From the susceptibility and specific heat measurements Deutz et al [1] have concluded that TmIn 3 orders antiferromagnetically at a temperature of 1.6 K. Analysis of the specific heat in terms of a crystal-field Hamiltonian enables the authors to deduce the possible sets of crystal-field parameters yielding the crystal-field splitting schemes with a singlet ground state, provided that small tetragonal distortion of the crystal lattice occurs. A somewhat different conclusion on the crystal-field scheme in TmIn 3 has been drawn by Mrachkov et al [2] from their own high field magnetization and susceptibility experiments. These authors suggest that the ground state of TmIn 3 is the nonmagnetic doublet G 3 and the first excited state is the triplet G ð1Þ 5 .…”

Magnetic, transport and thermal properties of ternary indides R2CoIn8(R = rare earths and Y)

“…The crystal field splits the 2J + 1-fold degenerate ground state to several sublevels. In the case of a rare earth ion possessing an even number of 4f electrons, a non-magnetic ground state is expected, a non-magnetic singlet [11] or rarely a non-magnetic doublet [20]. The non-magnetic ground state would remain stable down to very low temperature if the exchange interactions do not exceed a certain critical value [21].…”

“…The ground state is a non-magnetic doublet, which is rarely found. A few reported cases are TmIn 3 and TmAl 3 [20,23]. Figure 8(a) shows the total resistivity curve for Pr 2 CoIn 8 from 2 to 300 K. The curve is fitted to the Bloch-Grüneisen relation (equation ( 2)).…”
