Electron transport and magnetic properties of the filled skutterudite compound ThFe4As12

Abstract: Single crystals of the filled skutterudite compound ThFe 4 As 12 were examined down to T = 0.4 K and in magnetic fields up to B = 9 T. Electron transport properties combined with results of Hall-effect measurements indicate semimetallic properties with a charge carrier density of the order of 2 × 10 20 cm-3. In terms of a two-band model, the effective mass of the electrons is nearly a factor of 5 larger than the hole effective mass. A small carrier density is in line with the lack of magnetic ordering in this … Show more

“…2 in Ref. [35]), which indicates the lack of magnetic order, and the specific heat divided by temperature yields a straight line against T 2 down to 2 K. On the other hand, the lowtemperature magnetization curves presented in the inset of Fig. 8 in this paper for ThFe 2 Al 10 are reminiscent of those for YFe 2 Al 10 (see the inset 1 in Ref.…”

“…For comparison, in Fig. 8 we have also plotted the magnetic data of the skutterudite ThFe 4 As 12 [35], for which the temperature variation of the susceptibility, χ(T), resembles that of ThFe 2 Al 10 , although the atomic Fe:Th ratio is twice as large for the arsenide. In such a situation, one would expect an insufficient number of electrons from the Th shell to fill up the 3d shell of iron completely.…”

“…Going from 4f to 5f elements, even more structural diversity may be expected. However, very few actinide-based iron–arsenic materials have been reported so far, perhaps as a result of synthesis complications imposed by toxicity, reactivity, and high vapor pressure of constituent elements. Prior to the current work, only one compound has been reported to exist in the uranium–iron–arsenic and thorium–iron–arsenic , systems. The arsenide UFeAs 2 (HfCuSi 2 structure type, space group P 4/ nmm ) was studied several decades ago, with measurements of physical properties impeded by the presence of impurities .…”

A skutterudite material ThFe 4 As 12 , was examined due to its unusual enhancement of the Sommerfeld coefficient, which remains unexplained.…”
