Antiferromagnetic Correlations in Strongly Valence Fluctuating CeIrSn

Abstract: CeIrSn with a quasikagome Ce lattice in the hexagonal basal plane is a strongly valence fluctuating compound, as we confirm by hard x-ray photoelectron spectroscopy and inelastic neutron scattering, with a high Kondo temperature of T K ∼ 480 K. We report a negative in-plane thermal expansion α=T below 2 K, which passes through a broad minimum near 0.75 K. Volume and a-axis magnetostriction for Bka are markedly negative at low fields and change sign before a sharp metamagnetic anomaly at 6 T. These behaviors ar… Show more

“…Hence, the energy difference to the Ce 4 f is larger by this amount. This is very much in agreement with the CI results that find an increase of the effective binding energy of the Ce 4 f electrons, ε 4 f , by about the same energy when going from CeRhSn to CeRh 0.25 Pd 0.75 Sn (see Table I) or with respect to CeIrSn [33]. Accordingly, the hybridization in the Pd rich samples is weaker than in CeRhSn and also weaker than in CeIrSn.…”

“…Here the respective spectral weights are indexed according to their 4 f occupation f 0 , f 1 , and f 2 in the initial state, and the regions of the f 2 spectral weight of the Ce 3d 5/2 core level and of the 4 f 0 of the Ce 3d 3/2 are blown-up in the insets. The strong f 0 intensity in CeRhSn suggests that the 4 f state is almost as strongly hybridized as in intermediate valent CeIrSn [33]. The 10% substitution of Rh by Pd has only a minor effect on the f spectral weights.…”

“…For example, in YbAgGe, as function of applied magnetic field, a series of almost degenerate magnetically ordered states arises below 1 K with a quantum bicritical metamagnetic endpoint and pronounced non-Fermi liquid behavior in its vicinity [9,10]. While in YbAgGe the 4f electrons are well localized due to a very weak Kondo in-teraction, isostructural CeRhSn and CeIrSn are Kondo lattices within the intermediate valence regime [11,12]. For CeRhSn zero-field quantum criticality was detected, which is tunable by in-plane uniaxial pressure and related to geometrical frustration [13,14].…”
