Magnetic properties of Ce(Ru1-xFex)2Al10

YbFe2Al10-type CeRu2Al10 exhibits a mysterious phase transition at 27 K. The isostructural CeFe2Al10 is a Kondo semiconductor, whose macroscopic properties are very similar to those of CeRu2Al10 at a pressure of ∼4 GPa. In order to clarify the relationship between the physical and chemical pressure effect on CeRu2Al10, we have performed measurements of the electrical resistivity, magnetic susceptibility and specific heat on pseudo-ternary Ce(Ru1-xFex)2Al10 single crystals. These results suggest that Ce(Ru1-xFex)2Al10 gives almost the same information as CeRu2Al10 under pressure, and furthermore the primary origin of the phase transition is not simple magnetic one.
