Quadrupolar ordering and dense kondo behaviour in SmSn3

Low Temperature Properties of the Cubic Kondo Lattice Systems SmTr2Al20(Tr= Ti, V, Cr)

“…Note that Kondo effect with logarithmic increase in Sm-based systems is quite rare and only observed in SmSn 3 and SmFe 4 P 12 to the best of our knowledge [18,21]. According to the Hamann's expression [22], the slope of − ln T behavior and thereby the size of the resistivity decreases with T K .…”

Magnetism and electronic structure of selected Gd1−xSmxIn3 compounds

“…The small value of saturation magnetization on Ce atom equals m ¼ 0.65m B can be also a trace of the crystal field but also spin fluctuations contribution [6]. The SmIn 3 compound exhibits magnetic phase transition into antiferomagnetic phase below T N ¼ 16 K [3,9]. The specific heat study performed earlier by Kasaya et al [9] shows the presence of three anomalies around T N , i.e., at about 14.7, 15.2 and 15.9 K. The presence of these anomalies was also confirmed by resistivity measurements [9].…”

Strong valence fluctuation effects in SmTr2Al20(Tr=T

“…SmB 6 is known as a canonical Kondo insulator with intermediate valence 3 . Although quite rare in Sm-based systems, the Kondo effect is observed in SmSn 3 and SmFe 4 P 12 as − ln T dependence of the resistivity 4,5 . Recent extensive work on filled skutterudite compounds 6,7 has elucidated that when located at a highly symmetric center of a cage, the Sm ion may induce interesting physical properties.…”
